Hi all,

I am new to the forum.

I have an integral that I am using, and I am unsure if I am computing the derivative of it correctly. I want to take the derivative of the following expression with respect to p:

int( p*[1-G(p-y)] + int(z*g(z)dz,-inf,p-y) dF(y) , -inf,inf)

where G is a CDF of z, and g is its pdf, and F is the CDF of y, -inf and inf are the bounds of the outer integral, and -inf and p-y are the bounds of the inner integral.

My calculation gives:

int( 1-G(p-y)-y*g(p-y) dF(y), -inf,inf ) where -inf and inf are the bounds of the integral.

Thanks for your help.

All the best,

Bob
