sphstat package

Package contents

sphstat: A Python package for inferential statistics on vectorial data on the unit sphere.

Spherical data arises in many different fields of science. sphstat provides the necessary tools to apply inferential statistics on data on the unit sphere. The package implements tests and algorithms for vectorial datagiven by Fisher, Lewis and Embleton [1]. Note that tests and methods for axial data have not yet been implemented as of version 0.1.0.
