概率分布(德语:Wahrscheinlichkeitsverteilung,英语:probability distribution)或简称分布,是概率论的一个概念。使用时可以有以下两种含义: 广义地,它指称随机变量的概率性质--当我们说概率空间中的两个随机变量X和Y具有同样的分布(或同分布)时,我们是无法用概率来区别他们的。换言之: 称X和Y为同分布的随机变量,当且仅当对任意事件,有成立。 但是,不能认为同分布的随机变量是相同的随机变量。 狭义地,它是指随机变量的概率分布函数。设X是样本空间上的随机变量,为概率测度,则称如下定义的函数是X的分布函数,或称累积分布函数(简称CDF): ,对任意实数定义。 具有相同分布函数的随机变量一定是同分布的,因此可以用分布函数来描述一个分布,但更常用的描述手段是概率密度函数(pdf)。 在常用的文献中,“分布”一词可指其广义和狭义,而“累计分布函数”或“分布函数”一词只能指称后者。为了不致混淆,下文中谈及上述的广义时使用“分布”一词;狭义时使用“分布函数”一词。
