I don't know that I understand your question.  Suppose we get rid of all the
other outcomes and just concentrate on the outcomes 2 and 3.  Now we
have a binomial.  Are you asking whether the covariates are all equal
to zero, or do you want further that the probability of each is one-half?

I am asking this because what test you use depends on the question you
are asking.  Indeed, if you have enough data, this thinking leads to a
way to proceed.

That was my intuition, too, but I was a little fuzzy on the test to use.
I couldn't convince myself that the models were nested

By showing that -logit- with two and -ologit-
with three give essentially equivalent results?
