The Simple Matching Coefficient (SMC) is a statistic used for comparing the similarity and diversity of sample sets.〔http://mines.humanoriented.com/classes/2010/fall/csci568/portfolio_exports/sdaugherty/similarity.html〕 Given two objects, A and B, each with n binary attributes, SMC is defined as: : Where: : represents the total number of attributes where ''A'' and ''B'' both have a value of 1. : represents the total number of attributes where the attribute of ''A'' is 0 and the attribute of ''B'' is 1. : represents the total number of attributes where the attribute of ''A'' is 1 and the attribute of ''B'' is 0. : represents the total number of attributes where ''A'' and ''B'' both have a value of 0. == See also == * Jaccard index 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Simple matching coefficient」の詳細全文を読む スポンサード リンク
