Hi, y is nominal (3 categories), x1 to 3 is scale. What I want is a regression, showing the probability to fall in one of the three categories of y according to the x. How can I perform such a regression in R? Thanks for your help S?ren
check: help("multinom", package = "nnet") I hope it helps. Best, Dimitris soeren.vogel at eawag.ch wrote:> Hi, > > y is nominal (3 categories), x1 to 3 is scale.

Soren, It sounds like you are new to R so I will refer you to some packages that I think some people would find more user friendly as beginners. Zelig is excellent. You could run a series of logistic regressions coding your dependent variables as follows (a versus b, a versus c, b versus c) See the website below http://gking.harvard.edu/zelig/docs/index.html Alternatively you could try Rattle See the website below http://rattle.togaware.com/rattle-features.html Or you could try Rcmder HTH Paul> soeren.vogel@eawag.ch wrote: > > Hi, > > y is nominal (3 categories), x1 to 3 is scale.
