Hi everybody,
I created a neural network for a regression analysis with package ANN, but
now I need to know which is the significance of each predictor variable in
explaining the dependent variable. I thought to analyze the weight, but I
don't know how to do it.
Thanks in advance,
Giulia Di

If you are using the nnet package, the caret package has a variable
importance method based on Gevrey, M., Dimopoulos, I., Lek, S. (2003).
