> I have 11 covariates in a possion model. Could someone give me some advise on STEPWISE selection? Seems SPTEWISE selection can't be used in poisson model. How should I find the final model? Thanks much.
First advice: Don't use stepwise.
David Cassell and I are working on a paper (accepted at NESUG, already given at NYASUG) entitled: Stopping Stepwise.
You can read it here:
Now, if you tell us more about what your data are like, what N is, what your DV is, what you're trying to find out, and so on, then we can provide advice. Please write to SAS-L, not just to me.
