RooArgSet is a container object that can hold multiple RooAbsArg objects.
RooRealVar represents a fundamental (non-derived) real valued object.
ConfInterval is an interface class for a generic interval in the RooStats framework.
LikelihoodInterval is a concrete implementation of the RooStats::ConfInterval interface.
