Implementation of the Chi2 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.
The parameter slice can have the values x, X, y or Y. The histograms are sliced along the corresponding axis, and the JTestChi2() test is applied to each slice.
The input parameter threshold
, is used to evaluate whether the test is passed or failed for each slice.
The evaluation is done by comparing the threshold
value with the result produced by the Chi2 test for each slice. The output of JTestChi2() is a p-value.
The parameter threshold
should therefore be a real value between 0 and 1.
