In this tutorial we will discuss one of the most important distributions in directional statistics. In particular, we show how to sample from the von Mises-Fisher distribution and how one can visualise the samples on the unit sphere. This distribution has applications in many different fields of study ranging from astrophysics to paleomagnetism.

In this tutorial we will discuss circular and directional statistics. How to visualise circular distributions and also how to sample one of the most useful circular distributions.
