http://web.mit.edu/fmkashif/spring_06_stat/hw5solutions.pdf WebThe Rayleigh distribution arises as the distribution of the square root of an exponentially distributed (or χ 2 2 -distributed) random variable. If X follows an exponential distribution with rate λ and expectation 1 / λ, then Y = X follows a Rayleigh distribution with scale σ = 1 / 2 λ and expectation π / ( 4 λ).
