GLM Procedure


The GLM procedure now forms classification groups using the full formatted length of the CLASS variable levels.

In addition, you can compute exact p -values for three of the four multivariate tests (Wilks' Lambda, the Hotelling-Lawley Trace, and Roy's Greatest Root) andanimproved F - approximation for the fourth (Pillai's Trace). The default MSTAT=FAPPROX in the MANOVA and REPEATED statements produces multivariate tests using approximations based on the F distribution. Specifying MSTAT=EXACT computes exact p -values for three of the four tests (Wilks' Lambda, the Hotelling-Lawley Trace, and Roy's Greatest Root) and an improved F -approximation for the fourth (Pillai's Trace).
