Detailed Description

Implementation of the Kolmogorov test for 2D histograms.


This class is derived from the abstract class JTest_t(). For a general description of the implementation of this and other tests derived from JTest_t(), see its documentation.
This test compares two 2D histograms. If the parameter slice() equals x, X y or Y, the histograms are sliced along the corresponding axis, and the JKolmogorovTest() test is applied to each slice.
If slice() equals n or N, the histograms are not sliced, and JKolmogorovTest2D() is applied.
The input parameter threshold(), is used to evaluate whether the test is passed or failed for each slice or for the full 2D distribution.
The evaluation is done by comparing the threshold() value with the result produced by JKolmogorovTest() or JKolmogorovTest2D(), which is a p-value.
The parameter threshold() should therefore be a real value between 0 and 1.

Kolmogorov test for sliced 2D histograms.


The histograms are sliced along the axis specified by the slice parameter. A slice per bin is made.
For each of the slices, the input parameter threshold is used to evaluate whether the test is passed or failed.
The evaluation is done by comparing the threshold value with the result of the Kolmogorov test. The output of the Kolmogorov test is a p-value.
The parameter threshold should therefore be a real value between 0 and 1. The fraction of failed tests is compared to the input parameter failuresThreshold. If this fraction is larger than failuresThreshold, the test fails.

Parameters
h1First histogram
h2Second histogram
thresholdThreshold value for the test result
failuresThresholdThreshold value for the test result
parameterNameName of the parameter used to test the histograms
testNameName of the test used to compare the histograms
sliceThe axis along which the histogram is sliced.
Returns
Test result.
