Stella, An obvious answer is ?step However, I'm having a bit of a problem with it, lately. I got it wording with backwards selection, then it didn't work when I changed the "direction" from "backward" to "both" (backwards and forwards). I would like to know whatever you find that works. Also, look at the procedures for logistic regression in the Design package. regards, Farrar
