However, there has no paper to discuss the performance of the two estimators under the Pitman\u2019s closeness criterion. This paper presents the comparison of the weighted mixed estimator and the ordinary least squares estimator using the Pitman\u2019s closeness criterion. A simulation study is performed to illustrate the performance of the weighted mixed estimator and the ordinary least squares estimator under the Pitman\u2019s closeness criterion.<\/jats:p>","DOI":"10.3233\/faia200695","type":"book-chapter","created":{"date-parts":[[2020,11,10]],"date-time":"2020-11-10T16:22:20Z","timestamp":1605025340000},"source":"Crossref","is-referenced-by-count":0,"title":["Comparison of Two Estimators of the Regression Coefficient Vector Under Pitman\u2019s Closeness Criterion"],"prefix":"10.3233","author":[{"given":"Jibo","family":"Wu","sequence":"first","affiliation":[{"name":"Chongqing Key Laboratory of Complex Data Analysis & Artificial Intelligence, Chongqing University of Arts and Sciences, Chongqing"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","Fuzzy Systems and Data Mining VI"],"original-title":[],"link":[{"URL":"http:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/FAIA200695","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,11,10]],"date-time":"2020-11-10T16:22:21Z","timestamp":1605025341000},"score":1,"resource":{"primary":{"URL":"http:\/\/ebooks.iospress.nl\/doi\/10.3233\/FAIA200695"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,11,9]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/faia200695","relation":{},"ISSN":["0922-6389","1879-8314"],"issn-type":[{"value":"0922-6389","type":"print"},{"value":"1879-8314","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,11,9]]}}}
