interp_polysph

Creates a sequence of points on the polysphere linearly
interpolating between two points extrinsically.

Kernel density estimation on the polysphere, (hyper)sphere, and
circle. Includes functions for density estimation, regression estimation,
ridge estimation, bandwidth selection, kernels, samplers, and homogeneity
tests. Companion package to García-Portugués and Meilán-Vila (2025)
