In probability theory and statistics, the Rayleigh distribution is a continuous probability distribution for nonnegative-valued random variables. Up to rescaling, it coincides with the chi distribution with two degrees of freedom. The distribution is named after Lord Rayleigh . A Rayleigh distribution is often … See more The probability density function of the Rayleigh distribution is $${\displaystyle f(x;\sigma )={\frac {x}{\sigma ^{2}}}e^{-x^{2}/(2\sigma ^{2})},\quad x\geq 0,}$$ where See more Consider the two-dimensional vector $${\displaystyle Y=(U,V)}$$ which has components that are bivariate normally distributed, centered at zero, and independent. Then See more Given a random variate U drawn from the uniform distribution in the interval (0, 1), then the variate $${\displaystyle X=\sigma {\sqrt {-2\ln U}}\,}$$ See more An application of the estimation of σ can be found in magnetic resonance imaging (MRI). As MRI images are recorded as complex images but most often viewed as magnitude images, … See more The raw moments are given by: $${\displaystyle \mu _{j}=\sigma ^{j}2^{j/2}\,\Gamma \left(1+{\frac {j}{2}}\right),}$$ where $${\displaystyle \Gamma (z)}$$ is the gamma function. The See more • $${\displaystyle R\sim \mathrm {Rayleigh} (\sigma )}$$ is Rayleigh distributed if $${\displaystyle R={\sqrt {X^{2}+Y^{2}}}}$$, where $${\displaystyle X\sim N(0,\sigma ^{2})}$$ and $${\displaystyle Y\sim N(0,\sigma ^{2})}$$ are independent See more • Circular error probable • Rayleigh fading • Rayleigh mixture distribution • Rice distribution See more WebJan 16, 2024 · The Rayleigh distribution is a continuous probability distribution.It owes its name to the English Lord Rayleigh (John William Strutt, 3rd Baron Rayleigh), who …
