Detailed Description

Implementation of the Chi2 test for 1D 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.
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 produced by JChi2Test(). The output of a Chi2 test is a p-value.
The parameter threshold() should therefore be a real value between 0 and 1.

Chi2 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 Chi2 test. The output of a Chi2 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 fraction of failed tests.
parameterNameName of the parameter used to test the histograms
testNameName of the test used to compare the histograms
optionsROOT options for the test.
sliceThe axis along which the histogram is sliced.
Returns
Test result.

Bin-by-Bin Chi2 comparison of 2D histograms.


The Chi distance between h1 and h2 is calculated for each bin, and compared to the chi2Threshold() parameter.
If the calculated Chi distance is above this threshold, the test is passed for that bin.
If the fraction of failures is above the input parameter outliersThreshold(), the test is failed.

Parameters
h1First object
h2Second object
outliersThresholdfraction of bins allowed to fail the test
chi2Thresholdp-value
parameterNameName of the parameter used to test the histograms
testNameName of the test used to compare the histograms
Returns
