ConfInterval is an interface class for a generic interval in the RooStats framework.
Definition: ConfInterval.h:35
SimpleInterval is a concrete implementation of the ConfInterval interface.
virtual Bool_t IsInInterval(const RooArgSet &) const
Method to determine if a parameter point is in the interval.
virtual Double_t ConfidenceLevel() const
return confidence level
virtual ~SimpleInterval()
Destructor.
SimpleInterval(const char *name=0)
Default constructor.
virtual Double_t UpperLimit()
virtual RooArgSet * GetParameters() const
return cloned list of parameters
virtual Double_t LowerLimit()
Bool_t CheckParameters(const RooArgSet &) const
check if parameters are correct (i.e. they are the POI of this interval)
virtual void SetConfidenceLevel(Double_t)
used to set confidence level. Keep pure virtual
SimpleInterval & operator=(const SimpleInterval &other)
Namespace for the RooStats classes.
