In such a situation, favorable ability estimates can be obtained by developing a prior distribution for the ability of learners based on past measurement results and performing Bayes estimation using the prior distribution. A normal distribution is generally used as a prior distribution; however, in the present study, ability estimation was done using an asymmetric lognormal distribution, which better suits a situation in which ability shows improvement. The results of the present simulation study showed that using a lognormal distribution as a prior distribution, rather than a normal distribution, enabled more favorable ability estimates to be obtained.","subitem_description_type":"Abstract"}]},"item_5_description_38":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_5_source_id_19":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03882152"}]},"item_5_text_39":{"attribute_name":"本文言語","attribute_value_mlt":[{"subitem_text_value":"日本語"}]},"item_5_text_42":{"attribute_name":"ID","attribute_value_mlt":[{"subitem_text_value":"BKK0000066"}]},"item_5_text_7":{"attribute_name":"Author","attribute_value_mlt":[{"subitem_text_value":"Fujimori, Susumu"}]},"item_5_text_8":{"attribute_name":"所属機関","attribute_value_mlt":[{"subitem_text_value":"文教大学人間科学部"}]},"item_5_text_9":{"attribute_name":"Institution","attribute_value_mlt":[{"subitem_text_value":"Bunkyo University, Faculty of Human Science"}]},"item_5_version_type_35":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"藤森, 進"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-03-22"}],"displaytype":"detail","filename":"BKK0000066.pdf","filesize":[{"value":"2.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"BKK0000066.pdf","url":"https://bunkyo.repo.nii.ac.jp/record/217/files/BKK0000066.pdf"},"version_id":"9ef18a46-5ac5-402b-93f2-64e9398c90e0"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"item response theory"},{"subitem_subject":"Bayes estimation"},{"subitem_subject":"prior distribution"},{"subitem_subject":"lognormal distribution"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"非対称事前分布を利用した能力母数の推定 : 成長を前提としたテスト場面への適用","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"非対称事前分布を利用した能力母数の推定 : 成長を前提としたテスト場面への適用"},{"subitem_title":"Ability Parameter Estimation Utilizing Asymmetric Prior Distribution : Application to a Testing Situation in Which Ability Shows Improvement"}]},"item_type_id":"5","owner":"3","path":["117"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-02-10"},"publish_date":"2009-02-10","publish_status":"0","recid":"217","relation_version_is_last":true,"title":["非対称事前分布を利用した能力母数の推定 : 成長を前提としたテスト場面への適用"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T18:50:15.528293+00:00"}
