Hi team, Based on positive feedback in this thread and approval by two maintainers, gh-16435 <https://github.com/scipy/scipy/pull/16435> adding `scipy.stats.directionalmean` recently merged. However, I see that the original proposal did not link to that PR or mention the name or interface of `directionalmean` in particular, so I thought I'd invite those interested to continue the discussion at: https://github.com/scipy/scipy/pull/16435 or, for more general thoughts, https://github.com/scipy/scipy/issues/12041 Matt On Sun, Jun 5, 2022 at 11:10 AM Pamphile Roy <roy.pamphile@gmail.com> wrote:
Hi Daniel,
I also think these would be interesting.
I am myself very interested in the sampling part, as we actually recently added poisson disk sampling which internally uses hypersphere sampling. I would be happy to help with this work.
Cheers, Pamphile (@tupui)

Yes, I think both have a place in scipy.stats. Thanks!

Hi everyone,
recently questions came up with regards to statistics on the unit sphere in scipy.
Issue 12041 <https://github.com/scipy/scipy/issues/12041> raises the question if spherical mean/variance should be added as descriptive statistics similar to circmean/circvar <https://docs.scipy.org/doc/scipy/reference/generated/scipy.stats.circvar.htm...> . The canonical reference for all things related to statistics on the unit sphere is "Directional Statistics" by Mardia & Jupp.
Another important basic functionality is the generation of random samples on the unit sphere: discussion was started in this issue <https://github.com/scipy/scipy/issues/16205> .
Any strong opinion against these? I think at least the random number generation is reimplemented every day around the world (done so myself at least 2 times) and would strongly benefit from being part of scipy.
