Computation of numerical integral involving convolution
I have to solve the following convolution related numerical integration problem in R or perhaps computer algebra system like Maxima.
Integral[({k(y)-l(y)}^2)dy]
where
k(.) is the pdf of a standard normal distribution
l(y)=integral[k(z)*k(z+y)dz] (standard convolution)
z and y are scalars
The domain of y is -inf to +inf.
The integral in function l(.) is an indefinite integral. Do I need to add any additional assumption on z to obtain this?
Thank you.
