WebThe probability density function for gamma is: f ( x, a) = x a − 1 e − x Γ ( a) for x ≥ 0, a > 0. Here Γ ( a) refers to the gamma function. gamma takes a as a shape parameter for a. When a is an integer, gamma reduces to the Erlang distribution, and when a = 1 to the exponential distribution. WebJul 25, 2016 · The probability density function for invgauss is: invgauss.pdf(x, mu) = 1 / sqrt(2*pi*x**3) * exp(-(x-mu)**2/(2*x*mu**2)) for x > 0. invgauss takes mu as a shape parameter. The probability density above is defined in the “standardized” form. To shift and/or scale the distribution use the loc and scale parameters.
