P ( x; s c a l e) = x s c a l e 2 e − x 2 2 ⋅ s c a l e 2. The Rayleigh distribution would arise, for example, if the East and North components of the wind velocity had identical zero-mean Gaussian distributions. Then the wind speed would have a Rayleigh distribution. Webrayleigh is a special case of chi with df=2. The probability density above is defined in the “standardized” form. To shift and/or scale the distribution use the loc and scale parameters. Specifically, rayleigh.pdf (x, loc, scale) is identically equivalent to rayleigh.pdf (y) / scale with y = (x - loc) / scale.

"WebThe Weibull distribution can approximate many other distributions: normal, exponential and so on. The Weibull curve is called a "bathtub curve," because it descends in the beginning (infant mortality); flattens out in the middle and ascends toward the end of life.
