Hi Steve,
Thanks so much for your comments and your reference. I will take a look - I used the sample code using the online NHANES code, and it worked. However, while I just tweaked my code to include my own variables, I was still unable to obtain RRs.

I had tried to put my code in previous messages, but it kept getting bounced, so I gave up...Let me try again.
I am using data from the adult California Health Interview Survey (CHIS). I am modeling a continuous predictor (composite) against a dichotomous outcome (fastf2 ). My code is as follows:

. svy : glm fastf2 composite, fam(bin) link(logit) eform

***RESULTS BELOW****

(running glm on estimation sample)

Jackknife replications (80)

                                                Replications       =        80
                                                Design df          =        79

Hope this goes through!
