用无界交换对方法研究非一致Berry-Esseen界

Non-uniform Berry-Esseen Bound by Unbounded Exchangeable Pair Approach

Dali Liu, Zheng Li, Hanchao Wang, Zengjing Chen

摘要:

本文介绍了一种新的技巧,得到了无界可交换对的正规逼近和非正规逼近的非一致Berry-Esseen界。该方法不依赖于Chen和Shao \cite{cls1, cls2}提出的浓度不等式,可应用于二次型、一般Curie-Weiss模型和独立性检验。特别地,我们关于独立性检验的非一致结果是在6阶矩条件下,而Chen和Shao \cite{cs2}的一致界需要24阶矩条件。

英文摘要:

In this paper, a new technique is introduced to obtain non-uniform Berry-Esseen bounds of normal and nonnormal approximation for unbounded exchangeable pairs. This technique does not rely on the concentration inequalities developed by Chen and Shao \cite{cls1, cls2} and can be applied to the quadratic forms, general Curie-Weiss model and an independence test. In particular, our non-uniform result about the independence test is under 6th moment condition, while the uniform bound in Chen and Shao \cite{cs2} requires 24th moment condition.
