Randomized incomplete $U$ -statistics in high dimensions

Xiaohui Chen, Kengo Kato

This paper studies inference for the mean vector of a high-dimensional $U$ -statistic. In the era of Big Data, the dimension $d$ of the $U$ -statistic and the sample size $n$ of the…

Finite sample change point inference and identification for high-dimensional mean vectors

Mengjia Yu, Xiaohui Chen

Cumulative sum (CUSUM) statistics are widely used in the change point inference and identification. For the problem of testing for existence of a change point in an independent sam…

Jackknife multiplier bootstrap: finite sample approximations to the $U$ -process supremum with applications

Xiaohui Chen, Kengo Kato

This paper is concerned with finite sample approximations to the supremum of a non-degenerate $U$ -process of a general order indexed by a function class. We are primarily intereste…
