Abstract : The purpose of this project was to compare several methods of typological analysis by using each method with a number of data sets. Typological analysis (also called cluster analysis) is concerned with aggregates of objects, each measured with respect to a number of attributes. The aim of these methods is to discover a meaningful ordering or classification scheme for the objects using no information other than the attribute measures and relations among the objects. Object similarity is one such relationship; this is typically quantified as either a Euclidian distance measure or as an index of angular separation, such as the product moment correlation coefficient.
