平稳过程的加权U-统计量

On weighted U-statistics for stationary processes

Tailen Hsing, Wei Biao Wu

摘要:

基于随机样本X_1,.,X_n的形式为U_n= \sum_{1\le i,j\le n} w_{i-j} K(X_i,X_j),其中K是固定对称可测函数,w_i是对称权。一大类统计量可以表示为加权U统计量或其变体。当样本观测值来自非线性时间序列和线性过程时,本文建立了U_n的渐近正态性。

英文摘要:

A weighted U-statistic based on a random sample X_1,...,X_n has the form U_n=\sum_{1\le i,j\le n}w_{i-j}K(X_i,X_j), where K is a fixed symmetric measurable function and the w_i are symmetric weights. A large class of statistics can be expressed as weighted U-statistics or variations thereof. This paper establishes the asymptotic normality of U_n when the sample observations come from a nonlinear time series and linear processes.
