Hi

When I estimate two way interactions using xi3 and a mlogit model,
the  rrr option is:

a) an Odds Ratio
b) a Prevalence rate Difference
c) a Risk-Density

Since the betas are the deviance from the 'grand mean' of betas I am
inclined to interpret it as a prevalence rate difference. I am
seriously doubting myself on this one... any help?

FYI: Data comes from national survey.
