WebRonald Fisher. Fisher's z-distribution is the statistical distribution of half the logarithm of an F -distribution variate : It was first described by Ronald Fisher in a paper delivered at the International Mathematical Congress of 1924 in Toronto. [1] Nowadays one usually uses the F -distribution instead. Weberative mixture-model approach to clustering directionaldata based on the von Mises-Fisher (vMF) distribution, which arises naturally for data distributed on the unit hypersphere. In particular, we derive and analyze two variants of the Expectation Maximization (EM) framework for estimating the mean and concentration parameters of this mixture.
