When the Criterion Variable Has Two Categories, the Technique Is
When the criterion variable has two categories, the technique is referred to as multiple discriminant analysis.
In two-group discriminant analysis it is possible to derive only one discriminant function.
In the discriminant analysis model, the coefficients, or weights (b), are estimated so that the groups differ as much as possible on the values of the discriminant function. This occurs when the ratio of between-group sum of squares to within-group sum of squares for the discriminant scores is at a maximum.
Also referred to as discriminant loadings, the structure correlations represent the simple correlations between the predictors and the discriminant function in discriminant analysis.
