st: Obtaining rrr's of margins after mlogit

[John Francis <francisj71@googlemail.com>]

Hi,

I have a question on obtaining margins as relative risk ratios instead
of probabilities after I run the mlogit command. The reason I want to
do this is so that I can put different catagories in relation to one
another.
I know that, in a binary logit model, I could simply set -
expression(exp(xb())) - to get ORs.
