An Empirical Comparison of EM Initialization Methods and Model Choice Criteria for Mixtures of Skew-Normal Distributions
We investigate, via simulation study, the performance of the EM algorithm for maximum likelihood estimation in finite mixtures of skew-normal distributions with component specific parameters. The study takes into account the initialization method, the number of iterations needed to attain a fixed st...
