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 $${\displaystyle U}$$ and $${\displaystyle V}$$ have density functions See more Given a random variate U drawn from the uniform distribution in the interval (0, 1), then the variate $${\displaystyle X=\sigma {\sqrt {-2\ln U}}\,}$$ has a Rayleigh distribution with parameter 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, the background data is Rayleigh distributed. Hence, the above formula can be used … 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 $${\displaystyle R={\sqrt {X^{2}+Y^{2}}}}$$, … See more • Circular error probable • Rayleigh fading • Rayleigh mixture distribution • Rice distribution See more Webexchange power with each other unless they share the same k or vector.
