Constructor & Destructor Documentation

PearsonsChiSquared()

npstat::PearsonsChiSquared::PearsonsChiSquared	(	double	minCountToUse,
		double	subtractForNDoFCalculation,
		bool	forUncertaintyUseReferenceOnly
	)

Constructor arguments are as follows:

minCountToUse – Only bins with reference counts above this cutoff (or bins with sum of reference and data above this cutoff in case the parameter "forUncertaintyUseReferenceOnly" is false) will be used to calculate the chi-square.

subtractForNDoFCalculation – The number to be subtracted from the number of bins passing the cut in order to calculate the number of degrees of freedom. This can be useful in case the reference distribution was fitted from data or normalized to the data.

forUncertaintyUseReferenceOnly – If true, only reference counts will be used to estimate variance of bin difference (otherwise the variance is set to the sum of data and reference).
