Statistics - Inverse Gamma Distribution
逆伽马分布是伽马概率密度函数的倒数，具有正形状参数 $ {\alpha, \beta} $ 和位置参数 ${ \mu } $。$ {\alpha} $ 控制高度。$ {\alpha} $ 越大，概率密度函数 (PDF) 越高。$ {\beta} $ 控制速度。它由以下公式定义。
Inverse Gamma Distribution is a reciprocal of gamma probability density function with positive shape parameters $ {\alpha, \beta } $ and location parameter $ { \mu } $. $ {\alpha } $ controls the height. Higher the $ {\alpha } $, taller is the probability density function (PDF). $ {\beta } $ controls the speed. It is defined by following formula.
