This book addresses these technique of model building implies only very general, soft dis- issues. tributional assumptions but does not present any testing methods, One of the nice features of the book, at least from the practi- confidence regions, or inferences. This chapter gives calculation tioner’s point of view, is that the authors select and recommend formulas for deriving solutions and covariance matrices for a num- a few clustering methods and provide interactive computer pro- ber of models-aggregate, factor, and component models, and grams to implement them.
