强嵌入,即随机变量序列的部分和过程与布朗运动之间的耦合,在概率和统计中有许多应用。我们延长Chatterjee的新的使用斯坦的方法为$\{-1,+1\}$值变量的一般类的离散分布,并提供$\log n$率耦合的部分和的独立变量的布朗运动,和结果耦合和适当的标准化交换变量的布朗桥。
Strong embeddings, that is, couplings between a partial sum process of a sequence of random variables and a Brownian motion, have found numerous applications in probability and statistics. We extend Chatterjee's novel use of Stein's method for $\{-1,+1\}$ valued variables to a general class of discrete distributions, and provide $\log n$ rates for the coupling of partial sums of independent variables to a Brownian motion, and results for coupling sums of suitably standardized exchangeable variables to a Brownian bridge.
