Statistics - Rayleigh Distribution
瑞利分布是一个连续概率密度函数的分布。它以英国瑞利勋爵的名字命名。此分布广泛用于以下目的:
The Rayleigh distribution is a distribution of continuous probability density function. It is named after the English Lord Rayleigh. This distribution is widely used for the following:
-
Communications - to model multiple paths of densely scattered signals while reaching a receiver.
-
Physical Sciences - to model wind speed, wave heights, sound or light radiation.
-
Engineering - to check the lifetime of an object depending upon its age.
-
Medical Imaging - to model noise variance in magnetic resonance imaging.
