## Usage Note *35273: *Can I get discriminant function scores or function coefficients in JMP?

**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). Details of the computations can be found in
Appendix A of the *JMP Statistics and Graphics Guide*.
