It is shown that the consistency rate depends on the magnitude of change. A simulation study is performed to evaluate finite sample properties of the Wilcoxon-type estimator in standard cases, as well as under heavy-tailed distributions and disturbances by outliers, and to compare it with a CUSUM-type estimator. It shows that the Wilcoxon-type estimator is equivalent to the CUSUM-type estimator in standard cases, but outperforms the CUSUM-type estimator in presence of heavy tails or outliers in the data.", "revisions": [ { "version": "v1", "updated": "2017-01-09T17:27:25.000Z" } ], "analyses": { "keywords": [ "robust estimation", "change-point location", "cusum-type estimator", "evaluate finite sample properties", "wilcoxon-type estimator" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
