st: RRR with CI from logit model

[Michael Ingre <Michael.Ingre@ipm.ki.se>]

Dear list

I have estimated a logit model and would like to present Relative Risk 
Ratios (RRR) comparing the risk at different levels of a scale used as 
a covariate in the model. Odds Ratios are easily calculated with 
-lincom-. RRRs are also easily calculated by just taking the ratio 
between predicted probabilities for different levels of the scale. It 
is also quite straight forward to calculate a confidence interval of 
the predicted probabilities. But how do I calculate Confidence 
Intervals of the risk ratios?

Thanks

Michael
