Dear members of the S+ list,
I am looking for a procedure that allows the prediction of the probability
to be in category A,B,C or D (nominal scale, not ordinal!) given the
predictors which can be as well as categorical and interval scaled. Very
similar to a logistic regression, but allowing for a nominally scaled
dependent variable with more than two categories.
An application would be to estimate the probability to be treated in
hospital A,B,C or D given the patients initial characteristics like
symptom severity, age, diagnosis etc...
I tried SAS proc CATMOD, but this allows only to a limited degree interval
scaled predictors.
Does anybody know if there is a procedure or library for S+ that can do
this kind of multinomial regression? Can I download it somewhere? Are
there references?
Thanks in advance!
Matthias
