%description
A collection of functions for directional data (including massive data,
with millions of observations) analysis. Hypothesis testing, discriminant
and regression analysis, MLE of distributions and more are included. The
standard textbook for such data is the "Directional Statistics" by Mardia,
K. V. and Jupp, P. E. (2000). Other references include a) Phillip J.
Paine, Simon P. Preston, Michail Tsagris and Andrew T. A. Wood (2018). "An
