new preprint: Change-Point Detection based on Weighted Two-Sample U-Statistics

A new preprint joint with Herold Dehling and Kata Vuk about „Change-Point Detection based on Weighted Two-Sample U-Statistics” is online at arXiv.

Abstract: We investigate the large-sample behavior of change-point tests based on weighted two-sample U-statistics, in the case of short-range dependent data. Under some mild mixing conditions, we establish convergence of the test statistic to an extreme value distribution. A simulation study shows that the weighted tests are superior to the non-weighted versions when the change-point occurs near the boundary of the time interval, while they loose power in the center.
