Mixture distributions are often used in mixture models, which are used to express probabilities of sub-populations within a larger population. == See also == * Mixture distribution * List of probability distributions 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「Rayleigh mixture distribution」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
