The use of generalized discriminant analysis as a descriptive technique which can be employed outside of the traditional analysis of variance studies is discussed. Examples based on real data are provided. (Author/JKS)

Decomposable models, which allow for the interdependence of structure among observable variables, are described. Each model is fully characterized by a set of conditional interdependence restrictions and can be visualized with an undirected as well as a special type of directed graph. (Author/JKS)

An approach to determining the number of factors to be retained from a factor analysis using split-half factor comparabilities is presented. The use of this approach in determining proper factor rotation is also discussed. (JKS)
