neural network

Hello,

when we fit a neural network model to a dataset and select the save formula option, the results are saved. For example, if I want to see the formula for H1_1, it is written as:

0.5 * ((-12.824088735563) + Match( :sex, 0, 6.99084931122274, 1, -(6.99084931122274 + 0) ) + -0.166405890007763 * :weight

+0.436280476305382 * :age + 2.18056058975802 * :tumor size + Match( :family, 0, -3.24492142132066, 1, -((-3.24492142132066) + 0) )

+Match( :hyper, 0, -0.695306127956332, 1, -((-0.695306127956332) + 0) ) + Match( :dissection,

0, 0.12239140444254,

1, -(0.12239140444254 + 0)

))

My question is, how are the coefficient numbers written in this formula obtained?

I'm fairly sure you should find some sort of an answer from JMP Documentation/Help for Neural Networks: Neural Networks (jmp.com)

You might find more information about the estimation methods in this technical report.
