One might need 54 categories if they have factorial structure: factors A,B,C,... with levels kA, kB, kC, .. such that 54 = kA x kB x kC x...

If so, log-linear modeling via -glm- or Adrian Mander's -ipf- would be an appropriate analysis

I want to estimate a multinomial logistic model with mlogit. But my dependent variable holds 54 categories. Now, when I try to run mlogit I am informed there are too many categories. Consulting the help file exerts that there is a maximum of 50 categories. Well, just 4 short . . . My data is such that ordered or stereotype logistic regression (with a maximum of 30 outcomes) does not apply. Is there any way to get stata to accept more than 50 outcomes?Such a model seems to me very very problematic. Are you extremely sure you want to do this for 54 categories, and that you have enough data and that your data is sufficiently well behaved to reliably estimate such a model? I cannot imagine any real world dataset in which such a model could be meaningfully estimated.
