Subject:   Re: cutoff scores for Discriminant?

The SPSS DISCRIMINANT output does not include cutoffs. In the case of two groups, it's not that hard to figure it out in terms of the single canonical discriminant function (if equal priors are used, just take the point half way between the two group centroids), but if there are two or more functions, it gets very complicated, as you'd have to describe lines cutting off areas in a two or higher dimensional space.
