WebJan 6, 2024 · The Rayleigh distribution is a continuous probability distribution used to model random variables that can only take on values equal to or greater than zero.. It has the following probability density function: f(x; σ) = (x/σ 2)e-x 2 /(2σ 2). where σ is the scale parameter of the distribution. Properties of the Rayleigh Distribution WebThe Rayleigh distribution is a distribution of continuous probability density function. It is named after the English Lord Rayleigh.
