scikit-gof 0.0.1

Variations on goodness of fit tests for SciPy.

Provides variants of Kolmogorov-Smirnov, Cramer-von Mises and Anderson-Darling goodness of fit tests for fully specified continuous distributions.

The Kolmogorov-Smirnov statistic distribution is (hopefully) somewhat more precise compared to what SciPy has to offer at the time of writing.

Example

>>> from scipy.stats import norm, uniform
>>> from skgof import ks_test, cvm_test, ad_test

>>> ks_test((1, 2, 3), uniform(0, 4))
GofResult(statistic=0.25, pvalue=0.97...)

>>> cvm_test((1, 2, 3), uniform(0, 4))
GofResult(statistic=0.04..., pvalue=0.95...)

>>> data = norm(0, 1).rvs(random_state=1, size=100)
>>> ad_test(data, norm(0, 1))
GofResult(statistic=0.75..., pvalue=0.51...)
>>> ad_test(data, norm(.3, 1))
GofResult(statistic=3.52..., pvalue=0.01...)

Installation

pip install scikit-gof

Requires recent versions of Python (> 3), NumPy (>= 1.10) and SciPy.
