CATREG (Categorical regression with optimal scaling using alternating least squares) quantifies
categorical variables using optimal scaling, resulting in an optimal linear regression
equation for the transformed variables. The variables can be given mixed optimal scaling
levels and no distributional assumptions about the variables are made.
