| Subject | st: Adding regression variables one step at a time using a macro |
| Date | Wed, 10 Mar 2010 16:52:47 +0000 |
Dear Statalisters Please could you advise me on how to write a macro so that I can add regression variables one step at a time for only non-missing cases. It is similar to a forward stepwise except that I want to choose which variables I add. At the moment, I am doing the following: Model 1 reg y x1 if y<. & x1<. Model 2 - add another var reg y x1 x2 if y<. & x1<. &x2<.
