i4->h1=w4
So first we make this computation :
sum=w0 + i1*w1 + i2*w2 + i3*w3 + i4*w4 (the transfert function)
And for computing h1 we use the classic sigmoid function :
h1=1/(1+exp(-sum)).
And for calculating the output we have those weights :
b->o=wo0
i1->o=wo1
i2->o=wo2
i3->o=wo3
i4->o=wo4
h1->o=wo5
h2->o=wo6
h3->o=wo7
h4->o=wo8
h5->o=wo9
And the ouput is computed as follows :
o=wo0+wo1*i1+wo2*i2+wo3*i3+wo4*i4+wo5*h1+wo6*h2+wo7*h3+wo8*h4+wo9*h5.
So I would like to know, where is our error. Is it the sigmoid function
that we used ? The transfert functio...

Test for multiple contrasts?
Hello,
I've fitted a parametric survival model by
> survreg(Surv(Week, Cens) ~ C(Treatment, srmod.contr),
> data = poll.surv.wo3)
where srmod.contr is the following matrix of contrasts:
