The ability parameter which is treated as a random variable, is regressed on the covariates. It is assumed that the ability parameter is normally distributed with the mean and variance which are functions of the covariates. A two-parameter logistic model is adopted as the probability model of an item response. It is shown that item parameters and hyperparameters in the ability distribution can be estimated simultaneously using the EM algorithm. Examples are provided, where the mean and standard deviation of the ability parameter are represented by polynomials of age for data of an adult intelligence test.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_1_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"32773","nameIdentifierScheme":"WEKO"}],"names":[{"name":"小笠原, 春彦","nameLang":"ja"}]}]},"item_1_publisher_6":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Behaviormetric Society of Japan","subitem_publisher_language":"en"}]},"item_1_relation_8":{"attribute_name":"item_1_relation_8","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.2333/bhmk.22.37","subitem_relation_type_select":"DOI"}}]},"item_1_rights_12":{"attribute_name":"権利表記","attribute_value_mlt":[{"subitem_rights":"ファイルの原本はJSTで公開されているものである。","subitem_rights_language":"ja"}]},"item_1_rights_13":{"attribute_name":"出版社版URI","attribute_value_mlt":[{"subitem_rights":"http://joi.jlc.jst.go.jp/JST.Journalarchive/bhmk1974/22.37","subitem_rights_language":"ja"}]},"item_1_source_id_11":{"attribute_name":"item_1_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AA12022276","subitem_source_identifier_type":"NCID"}]},"item_1_source_id_7":{"attribute_name":"ISSN / EISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-6964","subitem_source_identifier_type":"EISSN"}]},"item_1_subject_16":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"417","subitem_subject_language":"ja","subitem_subject_scheme":"NDC"}]},"item_1_subject_17":{"attribute_name":"NIIサブジェクト","attribute_value_mlt":[{"subitem_subject":"数学","subitem_subject_language":"ja","subitem_subject_scheme":"Other"}]},"item_1_version_type_15":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Ogasawara, Haruhiko","creatorNameLang":"en","creatorNameType":"Personal"}],"nameIdentifiers":[{"nameIdentifier":"2610","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-01-23"}],"displaytype":"detail","filename":"BHMK22_37.pdf","filesize":[{"value":"494.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"BHMK22_37.pdf","url":"https://barrel.repo.nii.ac.jp/record/1157/files/BHMK22_37.pdf"},"version_id":"5a87072c-e37e-47af-8b52-631692e9a0b8"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"item response theory","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"logistic model","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"structural model","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ability parameter","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"EM algorithm","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Structural model of ability distribution in the item response theory","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Structural model of ability distribution in the item response theory","subitem_title_language":"en"}]},"item_type_id":"1","owner":"17","path":["4","29"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-11-25"},"publish_date":"2008-11-25","publish_status":"0","recid":"1157","relation_version_is_last":true,"title":["Structural model of ability distribution in the item response theory"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2025-03-17T00:33:09.721217+00:00"}
