Discriminant Analysis is an alternative to logistic regression. In logistic regression, the classification variable is random and predicted by the continuous variables, whereas in discriminant analysis the classifications are fixed, and the Y variables are realizations of random variables. However, in both cases, the categorical value is predicted by the continuous.
There are several varieties of discriminant analysis. JMP implements linear and quadratic discriminant analysis, along with a method that blends both types. In linear discriminant analysis, it is assumed that the
