Re: [R] number of weights in multinom ?
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.

How can we interpret this number ? That is not what the message says: 'variable' is not a plural noun but an adjective, the antonym of 'fixed'. Package nnet is support software for a book: you need to do your own homework by reading it.

[R] number of weights in multinom ?
Hello, In the function multinom (package nnet), I get the following message after training for a model with 9 inputs and 6 classes (output) : # weights: 66 (50 variable) I understand that there are 50 variables in the model, but I don't understand the number 66. How can we interpret this number ?

[R] number of weights in multinom
Dear colleagues, In the function multinom (package nnet), I get the following message after training for a model with 9 inputs and 6 classes (output) : # weights: 66 (50 variable) I understand that there are 50 variables in the model, but I don't understand the number 66. How can we interpret this number ? Thank you very much.
