[R-sig-eco] getting continuous output from a multinomial model fitting

2013-09-27 Thread Agus Camacho
Dear list, i have the following problem. I want to predict the value of a variable in nature, call it "ecological success(ES)". For doing that, I made some virtual simulations with which I reached a "best model" explaining ecological success. In the simulation, ES is a categorical variable so I u

Do you have multiple measurements on individuals? If so, have you accounted for the "repeated measures"? If there are no multiple measurements on individuals, then maybe what explains a decrease in body size is a selection bias: only smaller individuals survive in later time periods resulting

I think if you write R-sig-geo mailing list, someone will might response your question. -- View this message in context: http://r-sig-ecology.471788.n2.nabble.com/kernelUD-function-tp7578261p7578420.html Sent from the r-sig-ecology mailing list archive at Nabble.com. __
