Uniform Cramér Moderate Deviations for Weighted Branching Process in a Random Environment
摘要
Abstract
Let(Yn)be a weighted branching process under an independent identically distributed random environment ξ.In this paper,we use the existence of the harmonic moment and the non-degeneracy and convergence of Wn to prove the uniform Cramér moderate deviations for log(Yn+n0/Yn0).Wn=Yn/EξYn is a non-negative martingale.This result extends branching process in a random environment to weighted case.关键词
