I have the book by W. Venables and B. Ripley, but I didn't find the answer.
Here is an explicit example : library(nnet) data(fgl) ir.glm <- multinom(type ~., data=fgl) # weights: 66 (50 variable) initial value 383.436526 iter 10 value 259.867465 iter 20 value 184.185706 iter 30 value 146.240801 iter 40 value 139.340485 iter 50 value 136.405273 iter 60 value 132.523057 iter 70 value 131.095461 iter 80 value 130.303792 iter 90 value 128.402012 iter 100 value 127.396942 final value 127.396942 stopped after 100 iterations I understand that there are 50 variable weights, but I still not understand the sense of the value '66' in this model. I'm sorry to spam the system; I'm using R-help for the first time. Franck Vermet.
