Using Categorical Variables in Discriminant Analysis.
Peer reviewed Peer reviewed
Huberty, Carl J.; And Others – Multivariate Behavioral Research, 1986
Three methods of transforming unordered categorical response variables are described: (1) analysis using dummy variables; (2) eigenanalysis of frequency patterns scaled relative to within-groups variance; (3) categorical variables analyzed separately with scale values generated so that the grouping variable and the categorical variable are…

Decomposable Models: A New Look at Interdependence and Dependence Structures in Psychological Research.
Peer reviewed Peer reviewed
Hodapp, Volker; Wermuth, Nanny – Multivariate Behavioral Research, 1983
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)
