StatsRayleighPDF

StatsRayleighPDF (x [, σ [, µ ]])​

The StatsRayleighPDF function returns the Rayleigh probability distribution function.

f(x;σ,μ)=x−μσ2exp⁡(−(x−μ)22σ2),\displaystyle f(x ; \sigma, \mu)=\frac{x-\mu}{\sigma^{2}} \exp \left(-\frac{(x-\mu)^{2}}{2 \sigma^{2}}\right),

with defaults σ=1 and µ=0. It returns NaN for σ<=0 and zero for x<=µ.
