I understand that mlogit allows you to type "RRR" to
get the relative risk ratio. My understanding is that
RRR is the ratio of probabilities, while odds ratio is
the ratio of odds.
Is this correct? If so, why can't I get an odds ratio
from mlogit?
Whatever you call it (and different programs call it different things) it is the exponentiated coefficient. Different programs call it the odds ratio, irr, rrr, exp(b). There was a discussion on stata list a little while back about what the best terminology was.
