在两个或更多维度上进行聚类的Bootstrap

Bootstrap with Clustering in Two or More Dimensions

Konrad Menzel

摘要:

我们提出了一个自举程序的数据,可能会表现出聚类在两个或更多的维度。我们使用广义U-统计量理论的见解来分析统计量的大样本属性,这些统计量是来自跨集群汇集的观察的样本平均值。如果均值没有聚类,则这些统计量的渐近分布可能是非标准的。我们表明,建议的自举程序是(a)逐点一致的任何固定的数据生成过程(DGP),(b)一致的,如果我们排除聚类的情况下,没有聚类的意思,和(c)提供任何DGP的改进,使限制分布是高斯分布。

英文摘要:

We propose a bootstrap procedure for data that may exhibit clustering in two or more dimensions. We use insights from the theory of generalized U-statistics to analyze the large-sample properties of statistics that are sample averages from the observations pooled across clusters. The asymptotic distribution of these statistics may be non-standard if there is no clustering in means. We show that the proposed bootstrap procedure is (a) point-wise consistent for any fixed data-generating process (DGP), (b) uniformly consistent if we exclude the case of clustering without clustering in means, and (c) provides refinements for any DGP such that the limiting distribution is Gaussian.
