Abstract
The von Mises-Fisher distribution is probably the most widely used distribution to model data on the (hyper)sphere. Characterized by the mean direction and concentration parameters, it is symmetrical about the mean direction. The Maximum Likelihood estimator for this parameter is the directional sample mean.
