然而,这个属性并不唯一地表征伽马分布。存在两个独立正同分布的随机变量Xu X2,它们的公共分布函数F(x)不同于密度(1)给出的分布函数,但其中的两个变量(2)是按照密度(3)分布的。一些这样的分布函数F(x)由以下密度给出:
However, this property does not characterize the gamma distribution uniquely. There exist pairs of independent positive identically distributed random variables Xu X2 whose common distribution function F(x) differs from the one given by the density (1), but where the quotients (2) are distributed according to the density (3). Some such distribution functions F(x) are given by the following densities
