摘要：Using Stein’s method and the Malliavin calculus of variations, we deriveexplicit estimates for the Gamma approximation of functionals of a Poissonmeasure. In particular, conditions are presented under which the distribution ofa sequence of multiple Wiener-Itˆo stochastic integrals with respect to a compensatedPoisson measure converges to a Gamma distribution. As an illustration, wepresent a quantitative version and a non-central extension of a classical theoremby de Jong in the case of degenerate U-statistics of order two. Several multidimensionalextensions, in particular allowing for mixed or hybrid limit theorems, arealso provided.
