Hello - I wish to bring to your kind notice a bug in Python. Given any matrix X. While trying to compute the CoVariance matrix of that matrix X, Python does NOT compute the CoVarianceof the given matrix X. Instead, Python comptes the CoVariance of the Transpose of the given matrix X. This appears to be a bug in Python. Please refer to the below website for a given matrix and what the result should be after the computation of it's CoVariance. And I have provided a screenshot of what Python is returning. https://www.itl.nist.gov/div898/handbook/pmc/section5/pmc541.htm Please let me know if you have any questions. Regards, Prakash
Hey Prakash, Thanks for your email, but I'm afraid this is not the right place for bug reports. This email list is for discussions around maintenance of the Python documentation. Check out the guide for handling/reporting bugs in Python or in the documentation: https://docs.python.org/3/bugs.html. Regards, Marco.

Prakash, Your code uses the numpy library, so can you please report this issue to the maintainers of numpy - which is a 3rd party library. This mailing list is for issues with the documentation of the core python products - for example those hosted on docs.python.org; and numpy is not a core python product. The numpy bug list is at https://github.com/numpy/numpy/issues Regards, Tony,
