Thanks Austin. I understand the parameter vector part of your explanation now. However, I thought the `depvars' is a macro that contains the entire list: "kenemr moremr and zaremr", just like its counterpart indvar may contain variables A B and C. So, how am I supposed to provide the list of left hand side variables?
