Finding Groups in Data: An Introduction to Cluster Analysis
"Cluster analysis is the increasingly important and practical
subject of finding groupings in data. The authors set out to write
a book for the user who does not necessarily have an extensive
background in mathematics. They succeed very well."
"Finding Groups in Data [is] a clear, readable, and interesting
presentation of a small number of clustering methods. In addition,
the book introduced some interesting innovations of applied value
to clustering literature."
—Journal of Classification
"This is a very good, easy-to-read, and practical book. It has
many nice features and is highly recommended for students and
practitioners in various fields of study."
An introduction to the practical application of cluster analysis, this text presents a selection of methods that together can deal with most applications. These methods are chosen for their robustness, consistency, and general applicability. This book discusses various types of data, including interval-scaled and binary variables as well as similarity data, and explains how these can be transformed prior to clustering.
