If you specify the -eform- option after a fractional logit model
(-glm- with the -link(logit)- and -vce(robust)- options) than you will
not get odds ratios but what I have called relative proportion ratios.
There is a discussion on how to use these in the help-file of
-betafit-. That discussion is also directly applicable to relative
proportion ratios from a fractional logit model.
Hope this helps,
Maarten
