Proposal: Automatic estimation of number of histogram bins for weighted data
by Jonathan Crall 25 Dec '21

25 Dec '21

Hi all, this is my first post on this mailing list. I'm writing to propose a method for extending the histogram bandwidth estimators to work with weighted data. I originally submitted this proposal to seaborn: https://github.com/mwaskom/seaborn/issues/2710 and mwaskom suggested I take it here. Currently the unweighted auto heuristic is a combination of the Freedman-Diaconis and Sturges estimator. For reference, these rules are as follows: Sturges: return the peak-to-peak ptp=(i.e. x.max() - x.min()) and number of data points total=x.size. Then divide ptp by the log of one plus the number of data points. ptp / log2(total + 2) Freedman-Diaconis: Find the interquartile-range of the data iqr=(np.subtract(*np.percentile(x, [75, 25]))) and the number of data points total=x.size, then apply the formula: 2.0 * iqr * total ** (-1.0 / 3.0). Taking a look at these it seems (please correct me if I'm missing something that makes this not work) that there is a simple extension to weighted data. If we can find a weighted replacement for p2p, total, and iqr, the formulas should work exactly the same in the weighted case. The p2p case seems easy. Even if the data points are weighed, that doesn't change the min and max. Nothing changes here. For total, instead of taking the size of the array (which implicitly assumes each data point has a weight of 1), just sum the weight to get total=weights.sum(). I believe the IQR is also computable in the weighted case. import numpy as np n = 10 rng = np.random.RandomState(12554) x = rng.rand(n) w = rng.rand(n) sorted_idxs = x.argsort() x_sort = x[sorted_idxs] w_sort = w[sorted_idxs] cumtotal = w_sort.cumsum() quantiles = cumtotal / cumtotal[-1] idx2, idx1 = np.searchsorted(quantiles, [0.75, 0.25]) iqr_weighted = x_sort[idx2] - x_sort[idx1] print('iqr_weighted = {!r}'.format(iqr_weighted)) # test this is the roughtly the same for the "unweighted case" # (wont be exactly the same because this method does not have interpolation) w = np.ones_like(x) w_sort = w[sorted_idxs] cumtotal = w_sort.cumsum() quantiles = cumtotal / cumtotal[-1] idx2, idx1 = np.searchsorted(quantiles, [0.75, 0.25]) iqr_weighted = x_sort[idx2] - x_sort[idx1] iqr_unweighted_repo = x_sort[idx2] - x_sort[idx1] print('iqr_unweighted_repo = {!r}'.format(iqr_unweighted_repo)) iqr_unweighted_orig = np.subtract(*np.percentile(x, [75, 25])) print('iqr_unweighted_orig = {!r}'.format(iqr_unweighted_orig)) This quick and dirty method if weighted quantiles give a close result (which is probably fine for a bandwidth estimator): iqr_weighted = 0.21964093625695036 iqr_unweighted_repo = 0.36649977003903755 iqr_unweighted_orig = 0.30888312408540963 And I do see there is an open issue / PR for weighted quantiles/percentiles: https://github.com/numpy/numpy/issues/8935 https://github.com/numpy/numpy/pull/9211 so this code could make use of that after it lands. Lastly, I think the most common case (or at least my case) for using a weighted histogram is to combine multiple histograms. In this case the number of estimated bins might be greater than the number of weighted data points, and a simple min condition on that number and the estimated number of bins should take care of that. Please let me know: thoughts / opinions / ideas on this topic. I did do some searching for related discussion, but I may have missed it, so point me to that if I missed it. Also if the reason this feature does not exist is because there is some theoretical problem with estimating bandwidth for weighted data that I'm unaware of, I'd be interested to learn about that (although I can't see that being the case because these are just heuristics after all, and I have validated that this works well in my own use-cases). -- -Dr. Jon Crall (him)

ANN: SciPy 1.8.0rc2 -- please test
by Tyler Reddy 21 Dec '21

21 Dec '21

Hi all, On behalf of the SciPy development team I'm pleased to announce the release candidate SciPy 1.8.0rc2. Please help us test this pre-release. Sources and binary wheels can be found at: https://pypi.org/project/scipy/ and at: https://github.com/scipy/scipy/releases/tag/v1.8.0rc2 <https://github.com/scipy/scipy/releases/tag/v1.8.0rc1> One of a few ways to install the release candidate with pip: pip install scipy==1.8.0rc2 ===================== SciPy 1.8.0 Release Notes ===================== Note: SciPy 1.8.0 is not released yet! SciPy 1.8.0 is the culmination of 6 months of hard work. It contains many new features, numerous bug-fixes, improved test coverage and better documentation. There have been a number of deprecations and API changes in this release, which are documented below. All users are encouraged to upgrade to this release, as there are a large number of bug-fixes and optimizations. Before upgrading, we recommend that users check that their own code does not use deprecated SciPy functionality (to do so, run your code with ``python -Wd`` and check for ``DeprecationWarning`` s). Our development attention will now shift to bug-fix releases on the 1.8.x branch, and on adding new features on the master branch. This release requires Python 3.8+ and NumPy 1.17.3 or greater. For running on PyPy, PyPy3 6.0+ is required. **************************** Highlights of this release **************************** - A sparse array API has been added for early testing and feedback; this work is ongoing, and users should expect minor API refinements over the next few releases. - The sparse SVD library PROPACK is now vendored with SciPy, and an interface is exposed via `scipy.sparse.svds` with ``solver='PROPACK'``. - A new `scipy.stats.sampling` submodule that leverages the ``UNU.RAN`` C library to sample from arbitrary univariate non-uniform continuous and discrete distributions - All namespaces that were private but happened to miss underscores in their names have been deprecated. **************** New features **************** `scipy.fft` improvements ================== Added an ``orthogonalize=None`` parameter to the real transforms in `scipy.fft` which controls whether the modified definition of DCT/DST is used without changing the overall scaling. `scipy.fft` backend registration is now smoother, operating with a single registration call and no longer requiring a context manager. `scipy.integrate` improvements ======================== `scipy.integrate.quad_vec` introduces a new optional keyword-only argument, ``args``. ``args`` takes in a tuple of extra arguments if any (default is ``args=()``), which is then internally used to pass into the callable function (needing these extra arguments) which we wish to integrate. `scipy.interpolate` improvements ========================= `scipy.interpolate.BSpline` has a new method, ``design_matrix``, which constructs a design matrix of b-splines in the sparse CSR format. A new method ``from_cubic`` in ``BSpline`` class allows to convert a ``CubicSpline`` object to ``BSpline`` object. `scipy.linalg` improvements ===================== `scipy.linalg` gained three new public array structure investigation functions. `scipy.linalg.bandwidth` returns information about the bandedness of an array and can be used to test for triangular structure discovery, while `scipy.linalg.issymmetric` and `scipy.linalg.ishermitian` test the array for exact and approximate symmetric/Hermitian structure. `scipy.optimize` improvements ======================= `scipy.optimize.check_grad` introduces two new optional keyword only arguments, ``direction`` and ``seed``. ``direction`` can take values, ``'all'`` (default), in which case all the one hot direction vectors will be used for verifying the input analytical gradient function and ``'random'``, in which case a random direction vector will be used for the same purpose. ``seed`` (default is ``None``) can be used for reproducing the return value of ``check_grad`` function. It will be used only when ``direction='random'``. The `scipy.optimize.minimize` ``TNC`` method has been rewritten to use Cython bindings. This also fixes an issue with the callback altering the state of the optimization. Added optional parameters ``target_accept_rate`` and ``stepwise_factor`` for adapative step size adjustment in ``basinhopping``. The ``epsilon`` argument to ``approx_fprime`` is now optional so that it may have a default value consistent with most other functions in `scipy.optimize`. `scipy.signal` improvements ===================== Add ``analog`` argument, default ``False``, to ``zpk2sos``, and add new pairing option ``'minimal'`` to construct analog and minimal discrete SOS arrays. ``tf2sos`` uses zpk2sos; add ``analog`` argument here as well, and pass it on to ``zpk2sos``. ``savgol_coeffs`` and ``savgol_filter`` now work for even window lengths. Added the Chirp Z-transform and Zoom FFT available as `scipy.signal.CZT` and `scipy.signal.ZoomFFT`. `scipy.sparse` improvements ====================== An array API has been added for early testing and feedback; this work is ongoing, and users should expect minor API refinements over the next few releases. Please refer to the `scipy.sparse` docstring for more information. ``maximum_flow`` introduces optional keyword only argument, ``method`` which accepts either, ``'edmonds-karp'`` (Edmonds Karp algorithm) or ``'dinic'`` (Dinic's algorithm). Moreover, ``'dinic'`` is used as default value for ``method`` which means that Dinic's algorithm is used for computing maximum flow unless specified. See, the comparison between the supported algorithms in `this comment <https://github.com/scipy/scipy/pull/14358#issue-684212523>`_. Parameters ``atol``, ``btol`` now default to 1e-6 in `scipy.sparse.linalg.lsmr` to match with default values in `scipy.sparse.linalg.lsqr`. Add the Transpose-Free Quasi-Minimal Residual algorithm (TFQMR) for general nonsingular non-Hermitian linear systems in `scipy.sparse.linalg.tfqmr`. The sparse SVD library PROPACK is now vendored with SciPy, and an interface is exposed via `scipy.sparse.svds` with ``solver='PROPACK'``. For some problems, this may be faster and/or more accurate than the default, ARPACK. ``sparse.linalg`` iterative solvers now have a nonzero initial guess option, which may be specified as ``x0 = 'Mb'``. The ``trace`` method has been added for sparse matrices. `scipy.spatial` improvements ====================== `scipy.spatial.transform.Rotation` now supports item assignment and has a new ``concatenate`` method. Add `scipy.spatial.distance.kulczynski1` in favour of `scipy.spatial.distance.kulsinski` which will be deprecated in the next release. `scipy.spatial.distance.minkowski` now also supports ``0<p<1``. `scipy.special` improvements ====================== The new function `scipy.special.log_expit` computes the logarithm of the logistic sigmoid function. The function is formulated to provide accurate results for large positive and negative inputs, so it avoids the problems that would occur in the naive implementation ``log(expit(x))``. A suite of five new functions for elliptic integrals: ``scipy.special.ellipr{c,d,f,g,j}``. These are the `Carlson symmetric elliptic integrals <https://dlmf.nist.gov/19.16>`_, which have computational advantages over the classical Legendre integrals. Previous versions included some elliptic integrals from the Cephes library (``scipy.special.ellip{k,km1,kinc,e,einc}``) but was missing the integral of third kind (Legendre's Pi), which can be evaluated using the new Carlson functions. The new Carlson elliptic integral functions can be evaluated in the complex plane, whereas the Cephes library's functions are only defined for real inputs. Several defects in `scipy.special.hyp2f1` have been corrected. Approximately correct values are now returned for ``z`` near ``exp(+-i*pi/3)``, fixing `#8054 <https://github.com/scipy/scipy/issues/8054>`_. Evaluation for such ``z`` is now calculated through a series derived by `López and Temme (2013) <https://arxiv.org/abs/1306.2046>`_ that converges in these regions. In addition, degenerate cases with one or more of ``a``, ``b``, and/or ``c`` a non-positive integer are now handled in a manner consistent with `mpmath's hyp2f1 implementation < https://mpmath.org/doc/current/functions/hypergeometric.html>`_, which fixes `#7340 <https://github.com/scipy/scipy/issues/7340>`_. These fixes were made as part of an effort to rewrite the Fortran 77 implementation of hyp2f1 in Cython piece by piece. This rewriting is now roughly 50% complete. `scipy.stats` improvements ==================== `scipy.stats.qmc.LatinHypercube` introduces two new optional keyword-only arguments, ``optimization`` and ``strength``. ``optimization`` is either ``None`` or ``random-cd``. In the latter, random permutations are performed to improve the centered discrepancy. ``strength`` is either 1 or 2. 1 corresponds to the classical LHS while 2 has better sub-projection properties. This construction is referred to as an orthogonal array based LHS of strength 2. In both cases, the output is still a LHS. `scipy.stats.qmc.Halton` is faster as the underlying Van der Corput sequence was ported to Cython. The ``alternative`` parameter was added to the ``kendalltau`` and ``somersd`` functions to allow one-sided hypothesis testing. Similarly, the masked versions of ``skewtest``, ``kurtosistest``, ``ttest_1samp``, ``ttest_ind``, and ``ttest_rel`` now also have an ``alternative`` parameter. Add `scipy.stats.gzscore` to calculate the geometrical z score. Random variate generators to sample from arbitrary univariate non-uniform continuous and discrete distributions have been added to the new `scipy.stats.sampling` submodule. Implementations of a C library `UNU.RAN <http://statmath.wu.ac.at/software/unuran/>`_ are used for performance. The generators added are: - TransformedDensityRejection - DiscreteAliasUrn - NumericalInversePolynomial - DiscreteGuideTable - SimpleRatioUniforms The ``binned_statistic`` set of functions now have improved performance for the ``std``, ``min``, ``max``, and ``median`` statistic calculations. ``somersd`` and ``_tau_b`` now have faster Pythran-based implementations. Some general efficiency improvements to handling of ``nan`` values in several ``stats`` functions. Added the Tukey-Kramer test as `scipy.stats.tukey_hsd`. Improved performance of `scipy.stats.argus` ``rvs`` method. Added the parameter ``keepdims`` to `scipy.stats.variation` and prevent the undesirable return of a masked array from the function in some cases. ``permutation_test`` performs an exact or randomized permutation test of a given statistic on provided data. ************************ Deprecated features ************************ Clear split between public and private API ================================ SciPy has always documented what its public API consisted of in :ref:`its API reference docs <scipy-api>`, however there never was a clear split between public and private namespaces in the code base. In this release, all namespaces that were private but happened to miss underscores in their names have been deprecated. These include (as examples, there are many more): - ``scipy.signal.spline`` - ``scipy.ndimage.filters`` - ``scipy.ndimage.fourier`` - ``scipy.ndimage.measurements`` - ``scipy.ndimage.morphology`` - ``scipy.ndimage.interpolation`` - ``scipy.sparse.linalg.solve`` - ``scipy.sparse.linalg.eigen`` - ``scipy.sparse.linalg.isolve`` All functions and other objects in these namespaces that were meant to be public are accessible from their respective public namespace (e.g. `scipy.signal`). The design principle is that any public object must be accessible from a single namespace only; there are a few exceptions, mostly for historical reasons (e.g., ``stats`` and ``stats.distributions`` overlap). For other libraries aiming to provide a SciPy-compatible API, it is now unambiguous what namespace structure to follow. See `gh-14360 <https://github.com/scipy/scipy/issues/14360>`_ for more details. Other deprecations =============== ``NumericalInverseHermite`` has been deprecated from `scipy.stats` and moved to the `scipy.stats.sampling` submodule. It now uses the C implementation of the UNU.RAN library so the result of methods like ``ppf`` may vary slightly. Parameter ``tol`` has been deprecated and renamed to ``u_resolution``. The parameter ``max_intervals`` has also been deprecated and will be removed in a future release of SciPy. ************************************** Backwards incompatible changes ************************************** - SciPy has raised the minimum compiler versions to GCC 6.3 on linux and VS2019 on windows. In particular, this means that SciPy may now use C99 and C++14 features. For more details see `here <https://docs.scipy.org/doc/scipy/reference/dev/toolchain.html>`_. - The result for empty bins for `scipy.stats.binned_statistic` with the builtin ``'std'`` metric is now ``nan``, for consistency with ``np.std``. - The function `scipy.spatial.distance.wminkowski` has been removed. To achieve the same results as before, please use the ``minkowski`` distance function with the (optional) ``w=`` keyword-argument for the given weight. ***************** Other changes ***************** Some Fortran 77 code was modernized to be compatible with NAG's nagfor Fortran compiler (see, e.g., `PR 13229 <https://github.com/scipy/scipy/pull/13229 >`_). ``threadpoolctl`` may now be used by our test suite to substantially improve the efficiency of parallel test suite runs. ********* Authors ********* * @endolith * adamadanandy + * akeemlh + * Anton Akhmerov * Marvin Albert + * alegresor + * Andrew Annex + * Pantelis Antonoudiou + * Ross Barnowski + * Christoph Baumgarten * Stephen Becker + * Nickolai Belakovski * Peter Bell * berberto + * Georgii Bocharov + * Evgeni Burovski * Matthias Bussonnier * CJ Carey * Justin Charlong + * Dennis Collaris + * David Cottrell + * cruyffturn + * da-woods + * Anirudh Dagar * Tiger Du + * Thomas Duvernay * Dani El-Ayyass + * Castedo Ellerman + * Donnie Erb + * Andreas Esders-Kopecky + * Livio F + * Isuru Fernando * Evelyn Fitzgerald + * Sara Fridovich-Keil + * Mark E Fuller + * Ralf Gommers * Kevin Richard Green + * guiweber + * Nitish Gupta + * h-vetinari * Matt Haberland * J.

NumPy 1.22.0rc3 released
by Charles R Harris 18 Dec '21

18 Dec '21

Hi All, On behalf of the NumPy team, I'm pleased to announce the release of NumPy 1.22.0rc3. NumPy 1.22.0rc3 is a big release featuring the work of 152 contributors spread over 602 pull requests. There have been many improvements, highlights are: - Annotations of the main namespace are essentially complete. Upstream is a moving target, so there will likely be further improvements, but the major work is done. This is probably the most user visible enhancement in this release. - A preliminary version of the proposed Array-API is provided. This is a step in creating a standard collection of functions that can be used across applications such as CuPy and JAX. - NumPy now has a DLPack backend. DLPack provides a common interchange format for array (tensor) data. - New methods for `quantile`, `percentile`, and related functions. Thenew methods provide a complete set of the methods commonly found in the literature. - A new configurable allocator for use by downstream projects. These are in addition to the ongoing work to provide SIMD support for commonly used functions, improvements to F2PY, and better documentation. The Python versions supported in this release are 3.8-3.10, Python 3.7 has been dropped. Note that 32 bit wheels are only provided for Python 3.8 and 3.9 on Windows, all other wheels are 64 bits on account of Ubuntu, Fedora, and other Linux distributions dropping 32 bit support. All 64 bit wheels are also linked with 64 bit integer OpenBLAS, which should fix the occasional problems encountered by folks using truly huge arrays. Wheels can be downloaded from PyPI <https://pypi.org/project/numpy/1.22.0rc3/>; source archives, release notes, and wheel hashes are available on Github <https://github.com/numpy/numpy/releases/tag/v1.22.0rc3>. Linux users will need pip >= 0.19.3 in order to install the manylinux2014 wheels. A recent version of pip is needed to install the universal2 macos wheels. *Contributors* A total of 151 people contributed to this release.

ANN: SciPy 1.8.0rc1 -- please test
by Tyler Reddy 12 Dec '21

12 Dec '21

Hi all, On behalf of the SciPy development team I'm pleased to announce the release candidate SciPy 1.8.0rc1. Please help us test this pre-release. Sources and binary wheels can be found at: https://pypi.org/project/scipy/ and at: https://github.com/scipy/scipy/releases/tag/v1.8.0rc1 One of a few ways to install the release candidate with pip: pip install scipy==1.8.0rc1 Current known issues with rc1: https://github.com/MacPython/scipy-wheels/issues/155 ==================== SciPy 1.8.0 Release Notes ==================== Note: SciPy 1.8.0 is not released yet! SciPy 1.8.0 is the culmination of 6 months of hard work. It contains many new features, numerous bug-fixes, improved test coverage and better documentation. There have been a number of deprecations and API changes in this release, which are documented below. All users are encouraged to upgrade to this release, as there are a large number of bug-fixes and optimizations. Before upgrading, we recommend that users check that their own code does not use deprecated SciPy functionality (to do so, run your code with ``python -Wd`` and check for ``DeprecationWarning`` s). Our development attention will now shift to bug-fix releases on the 1.8.x branch, and on adding new features on the master branch. This release requires Python 3.8+ and NumPy 1.17.3 or greater. For running on PyPy, PyPy3 6.0+ is required. **************************** Highlights of this release **************************** - A sparse array API has been added for early testing and feedback; this work is ongoing, and users should expect minor API refinements over the next few releases. - The sparse SVD library PROPACK is now vendored with SciPy, and an interface is exposed via `scipy.sparse.svds` with ``solver='PROPACK'``. - A new `scipy.stats.sampling` submodule that leverages the ``UNU.RAN`` C library to sample from arbitrary univariate non-uniform continuous and discrete distributions - All namespaces that were private but happened to miss underscores in their names have been deprecated. *************** New features *************** `scipy.fft` improvements ================== Added an ``orthogonalize=None`` parameter to the real transforms in `scipy.fft` which controls whether the modified definition of DCT/DST is used without changing the overall scaling. `scipy.fft` backend registration is now smoother, operating with a single registration call and no longer requiring a context manager. `scipy.integrate` improvements ======================= `scipy.integrate.quad_vec` introduces a new optional keyword-only argument, ``args``. ``args`` takes in a tuple of extra arguments if any (default is ``args=()``), which is then internally used to pass into the callable function (needing these extra arguments) which we wish to integrate. `scipy.interpolate` improvements ========================= `scipy.interpolate.BSpline` has a new method, ``design_matrix``, which constructs a design matrix of b-splines in the sparse CSR format. A new method ``from_cubic`` in ``BSpline`` class allows to convert a ``CubicSpline`` object to ``BSpline`` object. `scipy.linalg` improvements ===================== `scipy.linalg` gained three new public array structure investigation functions. `scipy.linalg.bandwidth` returns information about the bandedness of an array and can be used to test for triangular structure discovery, while `scipy.linalg.issymmetric` and `scipy.linalg.ishermitian` test the array for exact and approximate symmetric/Hermitian structure. `scipy.optimize` improvements ======================= `scipy.optimize.check_grad` introduces two new optional keyword only arguments, ``direction`` and ``seed``. ``direction`` can take values, ``'all'`` (default), in which case all the one hot direction vectors will be used for verifying the input analytical gradient function and ``'random'``, in which case a random direction vector will be used for the same purpose. ``seed`` (default is ``None``) can be used for reproducing the return value of ``check_grad`` function. It will be used only when ``direction='random'``. The `scipy.optimize.minimize` ``TNC`` method has been rewritten to use Cython bindings. This also fixes an issue with the callback altering the state of the optimization. Added optional parameters ``target_accept_rate`` and ``stepwise_factor`` for adapative step size adjustment in ``basinhopping``. The ``epsilon`` argument to ``approx_fprime`` is now optional so that it may have a default value consistent with most other functions in `scipy.optimize`. `scipy.signal` improvements ===================== Add ``analog`` argument, default ``False``, to ``zpk2sos``, and add new pairing option ``'minimal'`` to construct analog and minimal discrete SOS arrays. ``tf2sos`` uses zpk2sos; add ``analog`` argument here as well, and pass it on to ``zpk2sos``. ``savgol_coeffs`` and ``savgol_filter`` now work for even window lengths. Added the Chirp Z-transform and Zoom FFT available as `scipy.signal.CZT` and `scipy.signal.ZoomFFT`. `scipy.sparse` improvements ====================== An array API has been added for early testing and feedback; this work is ongoing, and users should expect minor API refinements over the next few releases. Please refer to the `scipy.sparse` docstring for more information. ``maximum_flow`` introduces optional keyword only argument, ``method`` which accepts either, ``'edmonds-karp'`` (Edmonds Karp algorithm) or ``'dinic'`` (Dinic's algorithm). Moreover, ``'dinic'`` is used as default value for ``method`` which means that Dinic's algorithm is used for computing maximum flow unless specified. See, the comparison between the supported algorithms in `this comment <https://github.com/scipy/scipy/pull/14358#issue-684212523>`_. Parameters ``atol``, ``btol`` now default to 1e-6 in `scipy.sparse.linalg.lsmr` to match with default values in `scipy.sparse.linalg.lsqr`. Add the Transpose-Free Quasi-Minimal Residual algorithm (TFQMR) for general nonsingular non-Hermitian linear systems in `scipy.sparse.linalg.tfqmr`. The sparse SVD library PROPACK is now vendored with SciPy, and an interface is exposed via `scipy.sparse.svds` with ``solver='PROPACK'``. For some problems, this may be faster and/or more accurate than the default, ARPACK. ``sparse.linalg`` iterative solvers now have a nonzero initial guess option, which may be specified as ``x0 = 'Mb'``. The ``trace`` method has been added for sparse matrices. `scipy.spatial` improvements ====================== `scipy.spatial.transform.Rotation` now supports item assignment and has a new ``concatenate`` method. Add `scipy.spatial.distance.kulczynski1` in favour of `scipy.spatial.distance.kulsinski` which will be deprecated in the next release. `scipy.spatial.distance.minkowski` now also supports ``0<p<1``. `scipy.special` improvements ====================== The new function `scipy.special.log_expit` computes the logarithm of the logistic sigmoid function. The function is formulated to provide accurate results for large positive and negative inputs, so it avoids the problems that would occur in the naive implementation ``log(expit(x))``. A suite of five new functions for elliptic integrals: ``scipy.special.ellipr{c,d,f,g,j}``. These are the `Carlson symmetric elliptic integrals <https://dlmf.nist.gov/19.16>`_, which have computational advantages over the classical Legendre integrals. Previous versions included some elliptic integrals from the Cephes library (``scipy.special.ellip{k,km1,kinc,e,einc}``) but was missing the integral of third kind (Legendre's Pi), which can be evaluated using the new Carlson functions. The new Carlson elliptic integral functions can be evaluated in the complex plane, whereas the Cephes library's functions are only defined for real inputs. Several defects in `scipy.special.hyp2f1` have been corrected. Approximately correct values are now returned for ``z`` near ``exp(+-i*pi/3)``, fixing `#8054 <https://github.com/scipy/scipy/issues/8054>`_. Evaluation for such ``z`` is now calculated through a series derived by `López and Temme (2013) <https://arxiv.org/abs/1306.2046>`_ that converges in these regions. In addition, degenerate cases with one or more of ``a``, ``b``, and/or ``c`` a non-positive integer are now handled in a manner consistent with `mpmath's hyp2f1 implementation < https://mpmath.org/doc/current/functions/hypergeometric.html>`_, which fixes `#7340 <https://github.com/scipy/scipy/issues/7340>`_. These fixes were made as part of an effort to rewrite the Fortran 77 implementation of hyp2f1 in Cython piece by piece. This rewriting is now roughly 50% complete. `scipy.stats` improvements ===================== `scipy.stats.qmc.LatinHypercube` introduces two new optional keyword-only arguments, ``optimization`` and ``strength``. ``optimization`` is either ``None`` or ``random-cd``. In the latter, random permutations are performed to improve the centered discrepancy. ``strength`` is either 1 or 2. 1 corresponds to the classical LHS while 2 has better sub-projection properties. This construction is referred to as an orthogonal array based LHS of strength 2. In both cases, the output is still a LHS. `scipy.stats.qmc.Halton` is faster as the underlying Van der Corput sequence was ported to Cython. The ``alternative`` parameter was added to the ``kendalltau`` and ``somersd`` functions to allow one-sided hypothesis testing. Similarly, the masked versions of ``skewtest``, ``kurtosistest``, ``ttest_1samp``, ``ttest_ind``, and ``ttest_rel`` now also have an ``alternative`` parameter. Add `scipy.stats.gzscore` to calculate the geometrical z score. Random variate generators to sample from arbitrary univariate non-uniform continuous and discrete distributions have been added to the new `scipy.stats.sampling` submodule. Implementations of a C library `UNU.RAN <http://statmath.wu.ac.at/software/unuran/>`_ are used for performance. The generators added are: - TransformedDensityRejection - DiscreteAliasUrn - NumericalInversePolynomial - DiscreteGuideTable - SimpleRatioUniforms The ``binned_statistic`` set of functions now have improved performance for the ``std``, ``min``, ``max``, and ``median`` statistic calculations. ``somersd`` and ``_tau_b`` now have faster Pythran-based implementations. Some general efficiency improvements to handling of ``nan`` values in several ``stats`` functions. Added the Tukey-Kramer test as `scipy.stats.tukey_hsd`. Improved performance of `scipy.stats.argus` ``rvs`` method. Added the parameter ``keepdims`` to `scipy.stats.variation` and prevent the undesirable return of a masked array from the function in some cases. ``permutation_test`` performs an exact or randomized permutation test of a given statistic on provided data. *********************** Deprecated features *********************** Clear split between public and private API ================================ SciPy has always documented what its public API consisted of in :ref:`its API reference docs <scipy-api>`, however there never was a clear split between public and private namespaces in the code base. In this release, all namespaces that were private but happened to miss underscores in their names have been deprecated. These include (as examples, there are many more): - ``scipy.signal.spline`` - ``scipy.ndimage.filters`` - ``scipy.ndimage.fourier`` - ``scipy.ndimage.measurements`` - ``scipy.ndimage.morphology`` - ``scipy.ndimage.interpolation`` - ``scipy.sparse.linalg.solve`` - ``scipy.sparse.linalg.eigen`` - ``scipy.sparse.linalg.isolve`` All functions and other objects in these namespaces that were meant to be public are accessible from their respective public namespace (e.g. `scipy.signal`). The design principle is that any public object must be accessible from a single namespace only; there are a few exceptions, mostly for historical reasons (e.g., ``stats`` and ``stats.distributions`` overlap). For other libraries aiming to provide a SciPy-compatible API, it is now unambiguous what namespace structure to follow. See `gh-14360 <https://github.com/scipy/scipy/issues/14360>`_ for more details. Other deprecations =============== ``NumericalInverseHermite`` has been deprecated from `scipy.stats` and moved to the `scipy.stats.sampling` submodule. It now uses the C implementation of the UNU.RAN library so the result of methods like ``ppf`` may vary slightly. Parameter ``tol`` has been deprecated and renamed to ``u_resolution``. The parameter ``max_intervals`` has also been deprecated and will be removed in a future release of SciPy. ************************************** Backwards incompatible changes ************************************** - SciPy has raised the minimum compiler versions to GCC 6.3 on linux and VS2019 on windows. In particular, this means that SciPy may now use C99 and C++14 features. For more details see `here <https://docs.scipy.org/doc/scipy/reference/dev/toolchain.html>`_. - The result for empty bins for `scipy.stats.binned_statistic` with the builtin ``'std'`` metric is now ``nan``, for consistency with ``np.std``. - The function `scipy.spatial.distance.wminkowski` has been removed. To achieve the same results as before, please use the ``minkowski`` distance function with the (optional) ``w=`` keyword-argument for the given weight. ***************** Other changes ***************** Some Fortran 77 code was modernized to be compatible with NAG's nagfor Fortran compiler (see, e.g., `PR 13229 <https://github.com/scipy/scipy/pull/13229 >`_). ``threadpoolctl`` may now be used by our test suite to substantially improve the efficiency of parallel test suite runs. ********** Authors ********** * @endolith * adamadanandy + * akeemlh + * Anton Akhmerov * Marvin Albert + * alegresor + * Andrew Annex + * Pantelis Antonoudiou + * Ross Barnowski + * Christoph Baumgarten * Stephen Becker + * Nickolai Belakovski * Peter Bell * berberto + * Georgii Bocharov + * Evgeni Burovski * Matthias Bussonnier * CJ Carey * Justin Charlong + * Dennis Collaris + * David Cottrell + * cruyffturn + * da-woods + * Anirudh Dagar * Tiger Du + * Thomas Duvernay * Dani El-Ayyass + * Castedo Ellerman + * Donnie Erb + * Andreas Esders-Kopecky + * Livio F + * Isuru Fernando * Evelyn Fitzgerald + * Sara Fridovich-Keil + * Mark E Fuller + * Ralf Gommers * Kevin Richard Green + * guiweber + * Nitish Gupta + * h-vetinari * Matt Haberland * J.

NumPy 1.22. 0rc2 Release
by Charles R Harris 10 Dec '21

10 Dec '21

Hi All, On behalf of the NumPy team, I'm pleased to announce the release of NumPy 1.22.0rc1. NumPy 1.22.0rc1 is a big release featuring the work of 151 contributers spread over 589 pull requests. There have been many improvements, highlights are: - Annotations of the main namespace are essentially complete. Upstream is a moving target, so there will likely be further improvements, but the major work is done. This is probably the most user visible enhancement in this release. - A preliminary version of the proposed Array-API is provided. This is a step in creating a standard collection of functions that can be used across applications such as CuPy and JAX. - NumPy now has a DLPack backend. DLPack provides a common interchange format for array (tensor) data. - New methods for `quantile`, `percentile`, and related functions. Thenew methods provide a complete set of the methods commonly found in the literature. - A new configurable allocator for use by downstream projects. These are in addition to the ongoing work to provide SIMD support for commonly used functions, improvements to F2PY, and better documentation. The Python versions supported in this release are 3.8-3.10, Python 3.7 has been dropped. Note that 32 bit wheels are only provided for Python 3.8 and 3.9 on Windows, all other wheels are 64 bits on account of Ubuntu, Fedora, and other Linux distributions dropping 32 bit support. All 64 bit wheels are also linked with 64 bit integer OpenBLAS, which should fix the occasional problems encountered by folks using truly huge arrays. Wheels can be downloaded from PyPI <https://pypi.org/project/numpy/1.22.0rc2/>; source archives, release notes, and wheel hashes are available on Github <https://github.com/numpy/numpy/releases/tag/v1.22.0rc2>. Linux users will need pip >= 0.19.3 in order to install the manylinux2014 wheels. A recent version of pip is needed to install the universal2 macos wheels. *Contributors* A total of 151 people contributed to this release.
