【摘要】 先验分布的选取一直以来是贝叶斯学派研究的重点,尤其是在无先验信息的情况下如何确定先验分布是贝叶斯学派关心的焦点,文章根据Jeffreys提出的利用Fisher信息矩阵确定无信息先验分布的方法,给出伽玛分布在三种情况下的无信息先验.更多还原

【Abstract】 Selection of prior distribution is an emphases of Bayes school. Especially, how to give prior distribution on the condition of vague prior information become a focus of Bayes school. This paper is based on Fisher’s information matrix to confirm prior distribution given by Jeffreys, and provide three kinds of prior distribution for Gamma distribution.更多还原
