FittingTest_BestModelKolmogorov

FittingTest_BestModelKolmogorov(sample, distributionCollection)

Select the best model according to the Kolmogorov goodness-of-fit test.

Parameters

sample2-d sequence of float

Tested sample.

modelslist of Distribution

Tested distributions.

Returns

best_modelDistribution

The distribution that fits the sample best according to the test. This may raise a warning if the best model does not perform well.

best_resultTestResult

Best test result.
