Breakdown points for maximum likelihood estimators of location–scale mixtures
Breakdown points for maximum likelihood estimators of location–scale mixtures
ML-estimation based on mixtures of Normal distributions is a widely used tool for cluster analysis. However, a single outlier can make the parameter estimation of at least one of the mixture components break down. Among others, the estimation of mixtures of t-distributions by McLachlan and Peel [Finite Mixture Models (2000) …
