How do I use Neural Net model to predict data?
I have got the Neural net modeling estimated parameters:
X1, X2, X3, X4 are input
Y is output:
H1:intercept
H1:X1
H1:X2
H1:X3
H1:X4
H2:intercept
H2:X1
H2:X2
H2:X3
H2:X4
My first question: when I calculate the H1 as H1=1/(1+exp(-(intercept + Sum(H1:Xi*Xi)) is not the H1 value JMP provided.
My second question; I assume the H1 and H2 values from JMP calculation are correct and using the linear combination of t...
