Without making parametric assumptions on the component distributions, we investigate how one can identify the number of components from the distribution function of the observed data. When k ≥ 2, a lower bound on the number of components (M) is nonparametrically identifiable from the rank of a matrix constructed from the distribution function of the observed variables. Building on this identification condition, we develop a procedure to consistently estimate a lower bound on the number of components.","subitem_description_type":"Abstract"}]},"item_8_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"本文フィルはリンク先を参照のこと","subitem_description_type":"Other"}]},"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/2012/2012cf866ab.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":"Department of Economics, University of British Columbia"},{"subitem_text_value":"Faculty of Economics, University of Tokyo"}]},"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":"Kasahara, Hiroyuki"}],"nameIdentifiers":[{"nameIdentifier":"97166","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shimotsu, Katsumi"}],"nameIdentifiers":[{"nameIdentifier":"97167","nameIdentifierScheme":"WEKO"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"finite mixture","subitem_subject_scheme":"Other"},{"subitem_subject":"latent class analysis","subitem_subject_scheme":"Other"},{"subitem_subject":"nonnegative rank","subitem_subject_scheme":"Other"},{"subitem_subject":"rank estimation","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":"Nonparametric Identification and Estimation of the Number of Components in Multivariate Mixtures","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Nonparametric Identification and Estimation of the Number of Components in Multivariate Mixtures"}]},"item_type_id":"8","owner":"1","path":["7436","7434"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-05-31"},"publish_date":"2013-05-31","publish_status":"0","recid":"42218","relation_version_is_last":true,"title":["Nonparametric Identification and Estimation of the Number of Components in Multivariate Mixtures"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:14:22.563173+00:00"}
