Dear colleagues,
I'm trying to fit a multinomial logistic regression for an ordinal variable.  
I see in the help pages for multinom in nnet that one should scale the predictors from 0-1.  Is that really necessary?
Also: can anyone clarify what the difference between alternative-specific and individual specific variables are?
Yours, Simon Kiss
