We consider the approximation of d-dimensional weighted integrals of certai
n isotropic functions. We are mainly interested ill cases where d is large.
We show that the convergence rate of quasi-Monte Carlo for the approximati
on of these integrals is O(root logn/n). Since this is a worst case result,
compared to the expected convergence rate O(n(-1/2)) of Monte Carlo, it sh
ows the superiority of quasi-Monte Carlo for this type of integral. This is
much faster than the worst case convergence, O(log(d) n/n), of quasi-Monte
. Carlo.
