两个多元中心极限定理

Two multivariate central limit theorems

Elizabeth Meckes

摘要:

本文导出了用标准$k$维高斯随机向量逼近某些$n$维随机向量的秩$k$投影的显式误差界。的界限给出的条款$k$,$n$,和一个基础的$k$维空间,我们的项目。所考虑的随机向量是具有独立同分布分量的向量的两个推广。在第一种情况下,随机向量具有独立的分量,但不必具有相同的分布。第二种情况是有限个可交换的随机变量序列。

英文摘要:

In this paper, explicit error bounds are derived in the approximation of rank $k$ projections of certain $n$-dimensional random vectors by standard $k$-dimensional Gaussian random vectors. The bounds are given in terms of $k$, $n$, and a basis of the $k$-dimensional space onto which we project. The random vectors considered are two generalizations of the case of a vector with independent, identically distributed components. In the first case, the random vector has components which are independent but need not have the same distribution. The second case deals with finite exchangeable sequences of random variables.
