对数伽马分布是一种概率密度函数,具有正形状参数 $ {\alpha, \beta } $ 和位置参数 $ { \mu } $。它的定义如下式所示。
Log Gamma Distribution is a probability density function with positive shape parameters $ {\alpha, \beta } $ and location parameter $ { \mu } $. It is defined by following formula.
-
${\alpha}$ = positive shape parameter.
-
${\beta}$ = positive shape parameter.
-
${x}$ = random variable.
Following diagram shows the probability density function with three different parameter combinations.
