Dear Stalister,

I have a question regarding Stata 10 being a newbee on the field.

I am analyzing a DHS data set *(survey) and for  the bivariate crude
analysis I am used to   tabodds  however it is not supported by the
svy , so I guess  I would have to use the logistic command for binary
analysis but the output is not what I want i.e a crude odd ratio by
category. Can I proceed with the svy or the stratification is the only
solution?

Waiting for your help

Sahid
