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. (My imagination is finite
though, so it may exist)
