Separate-Slopes Model in GLM, GLZ, and PLS

Select Separate-slopes model as the Type of analysis on the GLM Startup Panel - Quick tab to specify analysis of covariance (ANCOVA or MANCOVA) designs, with separate slope parameters for each treatment level (or combinations of levels) of the categorical predictors (see Separate Slopes designs). In the subsequent Quick Specs dialog box, you can specify one or more categorical predictor variables, one or more continuous predictor variables, and one or more dependent variables. By default, STATISTICA will estimate and evaluate the model containing the categorical factors and the highest order interaction between the categorical factors with each covariate. For more information, refer to the Introductory Overview and the GLM - Index.
