We study the problem of multivariate integration on the unit cube for unbounded integrands. Our study is motivated by problems in statistics and mathematical finance, where unbounded integrands can arise as a result of using the cumulative inverse normal transformation to map the integral from the unbounded domain Rd to the unit cube [0, 1]d. We define a new space of functions which possesses the boundary behavior of those unbounded integrands arising from statistical and financial applications, however, we assume that the functions are analytic, which is not usually the case for functions from finance problems. Our new function space is a weighted tensor-product reproducing-kernel Hilbert space. We carry out a worstcase analysis in this space and show that good randomly shifted lattice rules can be constructed component-by-component to achieve a worst-case error of order O(n-1/2), where the implied constant in the big O notation is independent of d if the sum of the weights is finite...
