Abstract The present disclosure provides a method for evaluating a likelihood that a subject belongs to a certain group with respect to a classification attribute which has a binary classification, the method comprising: receiving a subject score regarding an observation value for the subject; using a relational expression established between the sensitivity and specificity with a score regarding the observation value serving as a parameter to acquire the sensitivity and specificity of the subject score when the subject score serves as the parameter; acquiring a prior probability for the attribute of the subject; and acquiring the likelihood that the subject belongs to the classification attribute peculiar to the subject on the basis of the sensitivity, specificity, and prior probability of the subject. La présente divulgation concerne un procédé pour évaluer une probabilité qu'un sujet appartienne à un certain groupe par rapport à un attribut de classification possédant une classification binaire, le procédé comprenant les étapes suivantes : réception d'un score de sujet concernant une valeur d'observation pour le sujet ; utilisation d'une expression relationnelle établie entre la sensibilité et la spécificité avec un score concernant la valeur d'observation servant de paramètre pour obtenir la sensibilité et la spécificité du score du sujet lorsque le score du sujet sert de paramètre ; obtention d'une probabilité antérieure pour l'attribut du sujet ; et obtention de la probabilité que le sujet appartienne à l'attribut de classification propre au sujet sur la base de la sensibilité, de la spécificité et de la probabilité antérieure du sujet. 本開示では、二項分類を有する分類属性について、対象があるグループに属する尤度を評価する方法であって、対象の観測値に関する対象スコアを受け取ることと、前記観測値に関するスコアを媒介変数とする感度と特異度との間で成立している関係式を用いて、前記対象スコアを前記媒介変数とした場合の、前記対象スコアの前記感度と前記特異度とを取得することと、前記対象の属性の事前確率を取得することと、前記対象の前記感度、前記特異度及び前記事前確率に基づいて、前記対象に特有な分類属性に属する尤度を取得することと、を備える方法が提供される。
