Multinomial logistic regression in JMP
I am trying to perform multinomial logistic regression in JMP. I am using example from IDRE-UCLA (http://www.ats.ucla.edu/stat/sas/dae/mlogit.htm). In this this example (hsbdemo data set) how can I specify the baseline category for prog using (ref = "2") and the reference group for ses using (ref = "1") while working in JMP?
