matrixfisher.mle

It returns the maximum likelihood estimate of the Matrix Fisher parameter F(3x3).

 Matrix Fisher distribution 

MLE of the Matrix Fisher distribution on SO(3)

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).
