WebbGroup-based Trajectory Models We used group-based trajectory models to classify patients by their observed medication adherence. We focused on this method because it … WebbPROC GENMOD initially parameterizes the CLASS variables by looking at the levels of the variables across the complete data set. If you have an unbalanced replication of levels across variables or BY groups, then the design matrix and the parameter interpretation might be different from what you expect.
