Thanks dear Dr. Vahid, I have learned a lot from you. I have a question: in my model, I have two categorical independent variables (groups and time) each with two levels and one continuous covariate (anxiety as a predictor). I followed the same procedure you explained. The point is that anxiety*groups*time is significant, but no postdoc (apart from plots) is generated. How can I know where the difference lies (for instance, whether the slopes [anxiety and dependent variable] of groups significantly differ in time 1 or whether the slopes of groups significantly differ in time 2). Thanks in advance.
