Rayleigh probability density function
WebRayleigh distribution is a continuous probability distribution for positive-valued random variables. The data can be given by the mean value and a lower bound, or by a parameter … WebThe Rayleigh distribution arises as the distribution of the square root of an exponentially distributed (or \chi^2_2 χ22 -distributed) random variable. If X X follows an exponential distribution with rate \lambda λ and expectation 1/\lambda 1/λ, then Y=\sqrt {X} Y = X follows a Rayleigh distribution with scale \sigma=1/\sqrt {2\lambda} σ ...
