Halima I don't know of an R or S program for polytomous logistic regression, but this model can be fitted using the GEE function. Indeed a rather more flexible family of models may be fitted this way. The method is not maximum likelihood but behaves very well in practice. For full details see http://www.mrc-bsu.cam.ac.uk/pub/publications/submitted/david_clayton/ordcat2.p s (a paper which was accepted many years ago subject to minor revision and never revised owing to extreme laziness).

Dear R-users I am introducing my collegue to R and she is interested to use R to perform Polytomous Logistic Regression called also Multi-category logistic regression. Is there any program in R doing this? Thank you so much for any feedback. I take this opportunity to thank people who were kind to answer my query about how to include a postscript file generated from R, in a latex file and without their answer, I could still be in trouble, Thank you so much. Warm Regards, Halima from Leiden -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
