The preliminary test Liu-type estimator is introduced when it is suspected that the regression parameter may be constraint to a subspace. We also compare the preliminary test Liu-type estimator to the preliminary test estimator, preliminary test ridge estimator and preliminary test Liu estimator in the mean squared error sense.<\/jats:p>","DOI":"10.3233\/faia220379","type":"book-chapter","created":{"date-parts":[[2022,10,31]],"date-time":"2022-10-31T09:32:04Z","timestamp":1667208724000},"source":"Crossref","is-referenced-by-count":0,"title":["Preliminary Test Estimator in a Linear Regression Model"],"prefix":"10.3233","author":[{"given":"Yong","family":"Li","sequence":"first","affiliation":[{"name":"School of Mathematics and Big Data, Chongqing University of Arts and Sciences, Chongqing, 402160, China"}]},{"given":"Lipei","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Mathematics and Big Data, Chongqing University of Arts and Sciences, Chongqing, 402160, China"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","Fuzzy Systems and Data Mining VIII"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/FAIA220379","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,10,31]],"date-time":"2022-10-31T09:32:15Z","timestamp":1667208735000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/FAIA220379"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,10,18]]},"ISBN":["9781643683461","9781643683478"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/faia220379","relation":{},"ISSN":["0922-6389","1879-8314"],"issn-type":[{"value":"0922-6389","type":"print"},{"value":"1879-8314","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,10,18]]}}}
