WebThe probability density function for levy is: f ( x) = 1 2 π x 3 exp. ⁡. ( − 1 2 x) for x >= 0. This is the same as the Levy-stable distribution with a = 1 / 2 and b = 1. The probability density above is defined in the “standardized” form. To shift and/or scale the distribution use the loc and scale parameters.
