Detailed Description

Implementation of the Runs 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.
This test uses the input parameter threshold to evaluate whether the test is passed or failed.
The evaluation is done by comparing the threshold value with the result of the runs test.
