Proc Genmod - odds ratio.

[GemmaR]

Hello there,

I am currently doing a Logistic Regression course and was wondering if there was a way to get PROC GENMOD to calculate the odds ratio.

Paul Allison's book suggests that there isn't but I wasn't sure if this has been updated in more recent version of SAS.

Thanks in advance!

I think this note may address your question:

There is a link in this note to a document showing examples of writing CONTRAST and ESTIMATE statements. Examples of computing odds ratios using these statements are given in that document. While an example using GENMOD is not specifically shown, the same method applies. You could easily change the example using the CONTRAST statement in LOGISTIC to use the ESTIMATE statement in GENMOD.
