马尔可夫链U-统计量的一个简单方差不等式及其应用

A simple variance inequality for U-statistics of a Markov chain with applications

Gersende Fort, Eric Moulines, Pierre Priouret, Pierre Vandekerkhove

摘要:

本文对U-统计量建立了一个简单的方差不等式,其随机变量序列是遍历马尔可夫链。这个不等式中的常数是显式的,并且依赖于马尔可夫链的混合率的可计算界。我们应用这个结果在接近最优的条件下导出了马尔可夫链的U-统计量的强大数定律。

英文摘要:

We establish a simple variance inequality for U-statistics whose underlying sequence of random variables is an ergodic Markov Chain. The constants in this inequality are explicit and depend on computable bounds on the mixing rate of the Markov Chain. We apply this result to derive the strong law of large number for U-statistics of a Markov Chain under conditions which are close from being optimal.
