cdf : str or callable If a string, it should be the name of a distribution in `scipy.stats`. If `rvs` is a string then `cdf` can be False or the same as `rvs`. If a callable, that callable is used to calculate the cdf. args : tuple, sequence, optional Distribution parameters,...

1. Tests based on comparison (“best fit”) with a given distribution, often specifiedin terms of its CDF. Examples are the Kolmogorov–Smirnov test, the Lillieforstest, the Anderson–Darling test, the Cramer–von Mises criterion, as well as theShapiro–Wilk and Shapiro–Francia tests.2. ...
