The method of cluster analysis in two phases, also called two-step cluster analysis, is an exploratory tool designed to reveal natural groupings of a data set, in order to generate information criteria, cluster frequencies, and descriptive statistics by cluster as well as bar and sector charts, and graphs showing the relevance of variables. The method of two-step cluster analysis has unique features compared to other methods of traditional clustering, including: an automatic procedure for calculating the optimal number of clusters, the ability to create models of clusters with both categorical and continuous variables, and the possibility of working with large data files.References
