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).
