Re: st: Use of the term 'relative risk ratio'

I have a reviewer who is grumbling about the use of 'relative risk ratio'
to describe the effect estimates from multinomial logistic regression. And
it's the second time this has happened. The reviewer feels that they ought
to be called odds ratios, to prevent confusion with relative risks (and
that is a good point).
If I wanted to stress that an odds ratio is multinomial instead of binomial
(or "vanilla-flavour" in Ronan's terminology), then I would call it a
multinomial odds ratio. The "RRR" of -mlogit- is definitely not a relative
risk ratio, although, in a case-control study, it may estimate a relative
risk ratio or even a plain relative risk.
I would like to preserve the distinction between vanilla-flavour odds
ratios and relative risk ratios, but am a little unhappy that the term is
causing more heat than light.
Has anyone else experienced the problem? Is there a more useful way of
describing RRRs out there?
I hope this helps.
