Hello, I've been working with "nnet" and now I'd like to use the weigths, from the fitted model, to iterpret some of variables impornatce. I used the following command: mts <- nnet(y=Y,x=X,size =4, rang = 0.1, decay = 5e-4, maxit = 5000,linout=TRUE) X is (m x n) Y is (m x 1) And then I get the coeficients by: Wts<-coef(mts)
b->h1 i1->h1 i2->h1 i3->h1 i4->h1 i5->h1 i6->h1 i7->h1 ... b->o h1->o h2->o h3->o h4->o ... I understood that I should get the predicted Y (hat(Y)) by: hat(Y)= (b->o)+((b->h1)sum(X[,1:m]*Wts[i1:m-h1]+X[,1:m]*Wts[i1:m-h2]+...+X[,1:m] *Wts[i1:m-h4]))*(h1->o)+ ((b->h2)sum(X[,1:m]*Wts[i1:m-h2]+X[,1:m]*Wts[i1:m-h2]+...+X[,1:m]*Wts[i1 :m-h4]))*(h2->o)+...) Am I missed some point on this definition of NNET. Thanks in advance, Best Regards, Marlon !!! ======================================================================= Attention: The information contained in this message and/or ...{{dropped}} ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
