Using Categorical Variables in Discriminant Analysis.
Huberty, Carl J; And Others
Three methods of transforming unordered categorical response variables are described. One is a method using dummy binary variables. The second method analyzes all categorical variables simultaneously and is based on an eigenanalysis of frequency patterns scaled relative to within-groups variance, jointly developed by J. E. Overall and J. A. Woodward. The third method, independently developed by R. A. Fisher and H. O. Lancaster, analyzes each categorical variable separately and yields scale values so that the grouping variable and the categorical variable are maximally correlated. Results of analyzing two real data sets are used to make some tentative comparisons. (Author)
