JTestResult JTestRuns_t::JRunsTest ( TH1 *  h1,
TH1 *  h2,
double  threshold,
std::string  testName,
std::string  parameterName 
)
inline

Implements the Wald-Wolfowitx runs test: https://en.wikipedia.org/wiki/Wald%E2%80%93Wolfowitz_runs_test In this, an expected number of runs and a standard deviation are computed from the number of bins and the number of "aboves" and "belows".

The test returns the difference between the observed number of runs and the expected number of runs, expressed in standard deviations. This is compared to the threshold input parameter.

Parameters
h1First histogram
h2Second histogram
threshold
parameterNameName of the parameter used to test the histograms
testNameName of the test used to compare the histograms

Runs 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 Runs test.
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.
testNameName of the test used to compare the histograms
parameterNameName of the parameter used to test the histograms
sliceThe axis along which the histogram is sliced.
Returns
Test result.
