Yes, I think both have a place in scipy.stats. Thanks! On Sun, Jun 5, 2022 at 5:55 AM Daniel Schmitz < danielschmitzsiegen@googlemail.com> wrote:
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.
