Cumulative density function scipy
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.
