Although the maximum likelihood method is the principle of this estimation, this model is a nonlinear model with a restrictive condition. At first, HASSELBLAD solved this model by using a new iteration method with a computer. Although his method was regarded as the steepest descent method or EM algorithm, it is proved to be an application of LAGRANGE's indeterminate multiplier method to the iteration method. Nowadays, we have other useful algorithms of optimization, especially MARQUARDT's method, for this estimation.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"Age-length key 法は数学的には混合分布のパラメータである各分布の比率を推定する方法である.統計学的には最尤法を用いればよいが,非線型モデルであり,しかも制限条件がついているため簡単ではない.この問題は HASSELBLADによって最初に厳密に解決された.彼の方法は計算機を用いた反復法で,最急降下法あるいはEMアルゴリズムと解釈されてきたが,実際にはラグランジュの未定乗数法の応用であることを証明する.現在では最適化法,特にマルカール法によってより一般的に解くことができる.","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Japan Sea National Fisheries Research Institute","subitem_publisher_language":"en"}]},"item_10002_radio_30":{"attribute_name":"作成者","attribute_value_mlt":[{"subitem_radio_item":["吉","田"],"subitem_radio_language":"ja"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"js_k_42_17_24","subitem_relation_type_select":"Local"}}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"日本農学文献記事索引(agriknowledge)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://agriknowledge.affrc.go.jp/RN/2010501370","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00186380","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0021-4620","subitem_source_identifier_type":"PISSN"}]},"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":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Akamine, Tatsuro","creatorNameLang":"en"},{"creatorName":"赤嶺, 達郎","creatorNameLang":"ja"},{"creatorName":"アカミネ, タツロウ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Akamine","familyNameLang":"en"},{"familyName":"赤嶺","familyNameLang":"ja"},{"familyName":"アカミネ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Tatsuro","givenNameLang":"en"},{"givenName":"達郎","givenNameLang":"ja"},{"givenName":"タツロウ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"2059","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"90371822","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=90371822"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"三重大学","affiliationNameLang":"ja"},{"affiliationName":"ミエダイガク","affiliationNameLang":"ja-Kana"},{"affiliationName":"Mie University","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"松宮, 義晴","creatorNameLang":"ja"},{"creatorName":"マツミヤ, ヨシハル","creatorNameLang":"ja-Kana"},{"creatorName":"Matsumiya, Yoshiharu","creatorNameLang":"en"}],"familyNames":[{"familyName":"松宮","familyNameLang":"ja"},{"familyName":"マツミヤ","familyNameLang":"ja-Kana"},{"familyName":"Matsumiya","familyNameLang":"en"}],"givenNames":[{"givenName":"義晴","givenNameLang":"ja"},{"givenName":"ヨシハル","givenNameLang":"ja-Kana"},{"givenName":"Yoshiharu","givenNameLang":"en"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"age-length key; optimization; indeterminate multiplier; EM algorithm; MARQUARDT's method","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":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"体長組成から年齢組成を推定するage-length key法の数学的解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"体長組成から年齢組成を推定するage-length key法の数学的解析","subitem_title_language":"ja"},{"subitem_title":"Mathematical Analysis of Age-Length Key Method for Estimating Age Composition from Length Composition","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716951426151"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-04-23"},"publish_date":"2024-04-23","publish_status":"0","recid":"2002474","relation_version_is_last":true,"title":["体長組成から年齢組成を推定するage-length key法の数学的解析"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-04-01T05:17:26.082699+00:00"}
