Rayleigh density function formula
WebThe other calculation is very similar. Let X be Rayleigh with parameter σ 2. Then X has density function x σ 2 e − x 2 / ( 2 σ 2) for x ≥ 0, and 0 elsewhere. Let Y = X 2. We find the density function f Y ( y) of Y. To do this, we first find the cdf F Y ( y) of Y. For y > 0, we have. F Y ( y) = Pr ( Y ≤ y) = Pr ( X 2 ≤ y) = Pr ( X ≤ ...
