The corresponding linear combination of the best location equivariant and the unrestricted unbiased estimators is minimax. Since the locations are restricted, it is reasonable to use the linear combination of the restricted estimators such as maximum likelihood estimators. In this paper, a necessary and sufficient condition for such restricted estimators to be minimax is derived, and it is shown that the restricted estimators are not minimax when the number of the location parameters is large. The condition for the minimaxity is examined for some specific distributions. Finally, similar problems of estimating the product and sum of the restricted scale parameters are studied, and it is shown that similar non-dominance properties appear when the number of the scale parameters is large.","subitem_description_type":"Abstract"}]},"item_8_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"Forthcoming in Journal of the Japan Statistical Society.","subitem_description_type":"Other"},{"subitem_description":"本文フィルはリンク先を参照のこと","subitem_description_type":"Other"}]},"item_8_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"98611","nameIdentifierScheme":"WEKO"}],"names":[{"name":"久保川, 達也"}]}]},"item_8_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本経済国際共同センター"}]},"item_8_relation_25":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.cirje.e.u-tokyo.ac.jp/research/dp/2010/2010cf749ab.html","subitem_relation_type_select":"URI"}}]},"item_8_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11450569","subitem_source_identifier_type":"NCID"}]},"item_8_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"335","subitem_subject_scheme":"NDC"}]},"item_8_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Center for International Research on the Japanese Economy"}]},"item_8_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Faculty of Economics, University of Tokyo"},{"subitem_text_value":"Department of Statistics, Rutgers University"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kubokawa, Tatsuya"}],"nameIdentifiers":[{"nameIdentifier":"98609","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Strawderman, William E."}],"nameIdentifiers":[{"nameIdentifier":"98610","nameIdentifierScheme":"WEKO"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Decision theory","subitem_subject_scheme":"Other"},{"subitem_subject":"linear combination","subitem_subject_scheme":"Other"},{"subitem_subject":"location parameter","subitem_subject_scheme":"Other"},{"subitem_subject":"maximum likelihood estimator","subitem_subject_scheme":"Other"},{"subitem_subject":"restricted parameter","subitem_subject_scheme":"Other"},{"subitem_subject":"restricted estimator","subitem_subject_scheme":"Other"},{"subitem_subject":"scale parameter","subitem_subject_scheme":"Other"},{"subitem_subject":"truncated estimator","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"Non-minimaxity of Linear Combinations of Restricted Location Estimators and Related Problems","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Non-minimaxity of Linear Combinations of Restricted Location Estimators and Related Problems"}]},"item_type_id":"8","owner":"1","path":["7436","7434"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-01-17"},"publish_date":"2017-01-17","publish_status":"0","recid":"42885","relation_version_is_last":true,"title":["Non-minimaxity of Linear Combinations of Restricted Location Estimators and Related Problems"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:18:01.652999+00:00"}
