Cluster analysis comprises a range of methods for classifying multivariate data into subgroups. By organizing multivariate data into such subgroups, clustering can help reveal the characteristics of any structure or patterns present. These techniques have proven useful in a wide range of areas such as medicine, psychology, market research and bioinformatics.This fifth edition of the highly successful Cluster Analysis includes coverage of the latest developments in the field and a new chapter dealing with finite mixture models for structured data.Real life examples are used throughout to demonstrate the application of the theory, and figures are used extensively to illustrate graphical techniques. The book is comprehensive yet relatively non-mathematical, focusing on the practical aspects of cluster analysis.Key Features: Presents a comprehensive guide to clustering techniques, with focus on the practical aspects of cluster analysisProvides a thorough revision of the fourth edition, including new developments in clustering longitudinal data and examples from bioinformatics and gene studies./li>Updates the chapter on mixture models to include recent developments and presents a new chapter on mixture modeling for structured dataPractitioners and researchers working in cluster analysis and data analysis will benefit from this book.

Hunt for Nazis is the first comprehensive account of the post-1945 efforts to bring Nazi war criminals who had escaped to South America to justice. The author shows that the Nazi hunt -- which resulted in spectacular cases like the kidnapping of Adolf Eichmann -- should not only be understood as part of the afterlife of the Third Reich, but that it also became an integral aspect of dealing with repression at the hands of authoritarian regimes in South America. Dissidents and human rights activists assumed that the escaped Nazi perpetrators and collaborators continued to be involved in violent crimes in the service of these new dictatorships.
