Function Documentation

configureConstrainedGammas()

void RooStats::HistFactory::Detail::configureConstrainedGammas	(	RooArgList const &	gammas,
		std::span< const double >	relSigmas,
		double	minSigma
	)

Configure constrained gamma parameters for fitting.

This function configures constrained gamma parameters for fitting. If a given relative sigma is less than or equal to zero or below a threshold, the gamma parameter is set to be constant. The function also sets reasonable ranges for the gamma parameter and provides a reasonable starting point for pre-fit errors.

Parameters

gammas	The gamma parameters to be configured.
sigmaRel	The relative sigma values to be used for configuring the limits and errors.
minSigma	The minimum relative sigma threshold. If a relative sigma is below this threshold, the gamma parameter is set to be constant.
