Splus is ideal for binary/binomial regression with logit or
probit links. Superb for diagnostic displays and other graphics.

GLIM is still a fine alternative especially if there are a number
of candidate models in the X variables

EGRET is a fine menu driven alternative... and it will do
conditional logistic regression along with the standard stuff.
