法向近似的Stein耦合

Stein couplings for normal approximation

Louis H. Y. Chen, Adrian Röllin

摘要:

在本文中,我们提出了使用Stein方法进行正态逼近的一般框架。我们介绍了新的概念,斯坦耦合,我们表明,它位于流行的方法,如本地的方法,可交换对,大小偏置和许多其他方法的核心。我们证明了几个定理,一旦发现Stein耦合,Wasserstein和Kolmogorov度量的正规逼近就成为常规。为了说明我们框架的通用性,我们给出了Hoeffding组合中心极限定理,经典占用方案中的泛函,具有固定点数的点模式的邻域统计量和子模式的随机选取顶点的分量的泛函,临界Erdos-Renyi随机图在所有这些情况下,我们使用新的非标准联轴器。

英文摘要:

In this article we propose a general framework for normal approximation using Stein's method. We introduce the new concept of Stein couplings and we show that it lies at the heart of popular approaches such as the local approach, exchangeable pairs, size biasing and many other approaches. We prove several theorems with which normal approximation for the Wasserstein and Kolmogorov metrics becomes routine once a Stein coupling is found. To illustrate the versatility of our framework we give applications in Hoeffding's combinatorial central limit theorem, functionals in the classic occupancy scheme, neighbourhood statistics of point patterns with fixed number of points and functionals of the components of randomly chosen vertices of sub-critical Erdos-Renyi random graphs. In all these cases, we use new, non-standard couplings.
