The Stein and Chen-Stein methods for functionals of non-symmetric Bernoulli processes. (English) Zbl 1329.60079
Summary: Based on a new multiplication formula for discrete multiple stochastic integrals with respect to non-symmetric Bernoulli random walks, we extend results of G. D. Reinert et al. [Electron. J. Probab. 15, 1703–1742 (2010; Zbl 1225.60046)] on the Gaussian approximation of symmetric Rademacher sequences to the setting of possibly non-identically distributed independent Bernoulli sequences. We also provide Poisson approximation results for these sequences, by following a method of G. Peccati [“The Chen-Stein method for Poisson functionals”, Preprint (2011), arXiv: 1112.5051]. Our arguments use covariance identities obtained from the Clark-Ocone representation formula in addition to those usually based on the inverse of the Ornstein-Uhlenbeck operator.
