Stepwise Logistic Regression in PROC LOGISTIC

Hello everybody,

I am in the process of learning the ins and outs of using PROC LOGISTIC to conduct stepwise logistic regression. One thing I noticed about in the help manual is that during the backwards elimination step of the stepwise procedure, it uses the Wald test to determine whether or not to remove an explanatory variable from the model. Is there a way to specify either the score test or the likelihood ratio test? I am asking because we know from Hauck and Donner (JASA 1977) that the Wald test displays unusual behavior when applied to logistic regression.

Thank you for your time.
