st: RE: dropping outcomes in mlogit

["Verkuilen, Jay" <JVerkuilen@gc.cuny.edu>]

>>At a fist glance, there seem not to be excess of collinearity among
sectors and outcomes. How can I explain than one of the three outcomes
is dropped?<<

I would guess perfect prediction due to some combination of your
predictors. I'm surprised Stata didn't complain about it. You should
cross-tablulate your data to see where it might have fallen.
