在概率论與数理統計领域,萊斯分布(Rice distribution或Rician distribution)是一種连续概率分布,以美国科学家Template:Le的名字命名,其概率密度函数为:
其中是修正的第一类零阶貝索函數(Bessel function)。当时,莱斯分布退化为瑞利分布。

极限情况
For large values of the argument, the Laguerre polynomial becomes (See Abramowitz and Stegun §13.5.1 Template:Wayback)
It is seen that as becomes large or becomes small the mean becomes and the variance becomes
