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 67 of file ToyMCSampler.cxx.

◆ Refresh()

void RooStats::NuisanceParametersSampler::Refresh ( )

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.
