We now discuss the main statistical approach to clustering and segmentation: mixture models. We examine a general form of such mixtures and describe the EM estimation algorithm. We consider problems of the model and its estimation that are related to identification, local optima, standard errors and the number of segments. Those issues provide the basic foundation for the chapters that follow.
