Performance of the EM algorithm on the identification of a mixture of Watson distributions defined on the hypersphere
We consider a set of n individuals described by p standardised variables, and we suppose that the individuals are previously selected from a population and the variables are a sample of variables assumed to come from a mixture of k bipolar Watson distributions defined on the hypersphere. In this con...
