chi2_counting()

double statistics::chi2_counting	(	std::vector< double > &	data,
		std::vector< double > &	model,
		std::vector< double > &	weights,
		int	x_min = -1,
		int	x_max = -1,
		const char *	type = "neyman" )

Parameters

data	Vector containing the data.
model	Vector containing the model.
weights	Vector containing the weights.
x_min	Minimum index for computation.
x_max	Maximum index for computation.
type	Type of chi2 measure (default is "neyman").

Returns

The computed chi2 value.
