Hopefully this is a silly question with an easy fix. However, my results from a binary logistic regression is providing me odds ratio estimates that do not equate to the exponentiated coefficient estimates. Does SAS calculate Odds Ratios in some other fashion? I have negative estimates, which I assumed would relate to an odds ratio under 1, but this is not always the case. That and the numbers just don't line up.

Thanks for any help,

Peter
