bump.
would like to know the answer too. I am about using nnet--multinom to
estimate a multinomial logit model, but are not sure if this function
handles categorical data input.
Thanks for any help.

Subject: [R] formatting data to be analysed using multinomial logistic
regression (nnet)
I am looking into using the multinomial logistic regression option in the
nnet library and have two questions about formatting the data.
1. Can data be analysed in the following format or does it need to be
transformed into count data, such as the housing data in MASS?
Id Crime paranoia hallucinate toc disorg crimhist age
1 2 1 0 1 0 1 25
2 2 0 1 1 1 1 37
3 1 1 0 1 1 0 42
4 3 0 0 0 0 1 25
5 2 1 0 1 0 0 49
2.Can a ratio variable such as $age be included into a model, such as
the one below?
crimepred - glm (crime ~ paranoia + hallucinate + toc + crimhist,
family
= poisson, data = mht )
Any assistance with the above is appreciated,
regards
Bob Green
