Mixture models are a powerful tool for analyzing complex and heterogeneous datasets across many scientific fields from finance to genomics. Mixture Models: Parametric Semiparametric and New Directions provides an up-to-date introduction to these models their recent developments and their implementation using R. It fills a gap in the literature by covering not only the basics of finite mixture models but also recent developments such as semiparametric extensions robust modeling label switching and high-dimensional modeling. Features Comprehensive overview of the methods and applications of mixture models Key topics include hypothesis testing model selection estimation methods and Bayesian approaches Recent developments such as semiparametric extensions robust modeling label switching and high-dimensional modeling Examples and case studies from such fields as astronomy biology genomics economics finance medicine engineering and sociology Integrated R code for many of the models with code and data available in the R Package MixSemiRob Mixture Models: Parametric Semiparametric and New Directions is a valuable resource for researchers and postgraduate students from statistics biostatistics and other fields. It could be used as a textbook for a course on model-based clustering methods and as a supplementary text for courses on data mining semiparametric modeling and high-dimensional data analysis. .
