Hi Everyone, I am trying to enter variables in blocks using SAS 9.4 in a way analogous to how SPSS does this. Here are the variables in this simplified example. Dependent: Anxiety Test Score, "ANX" Independent: Age, Gender, Education, Depression Measure score ("Depres"), Coping Measure score ("Cope"). What I'd like to do is regress "ANX" on "Depres" and"Cope," entered together as one "block" of variables," then in the same modelion, regress ANX on a second block of variables, "Age," "Gender," and "Education." In this way, I can tell if the relationship between "ANX" and the first variable block (psychological test scores) changes when I introduce the second block (demographic variables). I'm not really interested in doing stepwise regression (i.e., forward or backward selection), just this fairly simple analysis. All I can tell from the documentation is that perhaps I indicate blocks by putting parentheses around the blocks of variables, but I'm not really sure if this is correct. Could anyone help me with this simple, I think, ,problem? This following states the problem in (sort of) SAS language. proc reg data=Cohort.Anxiety; model Anx = (enter first block of variables); (enter second block of variables); run; Thank you very much!
