RooStats::NuisanceParametersSampler Class Reference

Helper class for ToyMCSampler.

Handles all of the nuisance parameter related functions. Once instantiated, it gives a new nuisance parameter point at each call to nextPoint(...). Only used inside ToyMCSampler, ie "private" in the cxx file

Member Function Documentation

NextPoint()

void RooStats::NuisanceParametersSampler::NextPoint	(	RooArgSet &	nuisPoint,
		Double_t &	weight
	)

Assigns new nuisance parameter point to members of nuisPoint.

nuisPoint can be more objects than just the nuisance parameters.

Definition at line 68 of file ToyMCSampler.cxx.

Refresh()

void RooStats::NuisanceParametersSampler::Refresh ( )

protected

Creates the initial set of nuisance parameter points.

It also refills the set with new parameter points if called repeatedly. This helps with adaptive sampling as the required number of nuisance parameter points might increase during the run.
