Can I get discriminant function scores or function coefficients?
Version 5.1.2 and higher: Yes. Discriminant analysis is available with the Analyze > Multivariate Methods > Discriminant menu selection. To get the discriminant scores, select Score Options > Save Formulas. Version 4 and Version 5.0: Yes. See pp. 334-335 of JMP Statistics and Graphics Guide, V4 or pp. 333-334 of JMP Statistics and Graphics Guide, V5 or pp. 513-514 of JMP Statistics and Graphics Guide, V6 for a general description and detailed formulas. If you select Save Discrim from the Manova Fit pull-down menu, you’ll get additional columns in the data table with the Mahalanobis distances and posterior probabilities. The values in the DIST variables are the Mahalanobis distances of each observation to the group centroids and could be called the scores on the discriminant functions. Each of these columns has a formula associated with it. If you look at the formula for the DIST variables, you see the coefficients of the functions used in JMP (which are not the same as those in SAS). D
