Abstract

Consider a measure μλ=xξxδx\mu_\lambda = \sum_x \xi_x \delta_x where the sum is over points xx of a Poisson point process of intensity λ\lambda on a bounded region in dd-space, and ξx\xi_x is a functional determined by the Poisson points near to xx, i.e. satisfying an exponential stabilization condition, along with a moments condition (examples include statistics for proximity graphs, germ-grain models and random sequential deposition models). A known general result says the μλ\mu_\lambda-measures (suitably scaled and centred) of disjoint sets in RdR^d are asymptotically independent normals as λ\lambda \to \infty; here we give an O(λ1/(2d+ϵ))O(\lambda^{-1/(2d + \epsilon)}) bound on the rate of convergence. We illustrate our result with an explicit multivariate central limit theorem for the nearest-neighbour graph on Poisson points on a finite collection of disjoint intervals.
