Class Description

 TConfidenceLevel

 Class to compute 95% CL limits

TConfidenceLevel()

 Default constructor

TConfidenceLevel(Int_t mc, bool onesided)

 a constructor that fix some conventions:
 mc is the number of Monte Carlo experiments
 while onesided specifies if the intervals are one-sided or not.

~TConfidenceLevel()

 The destructor

Double_t GetExpectedStatistic_b(Int_t sigma) const

 Get the expected statistic value in the background only hypothesis

Double_t GetExpectedStatistic_sb(Int_t sigma) const

 Get the expected statistic value in the signal plus background hypothesis

Double_t CLb(bool use_sMC) const

 Get the Confidence Level for the background only

Double_t CLsb(bool use_sMC) const

 Get the Confidence Level for the signal plus background hypothesis

Double_t CLs(bool use_sMC) const

 Get the Confidence Level defined by CLs = CLsb/CLb.
 This quantity is stable w.r.t. background fluctuations.

Double_t GetExpectedCLsb_b(Int_t sigma) const

 Get the expected Confidence Level for the signal plus background hypothesis
 if there is only background.

Double_t GetExpectedCLb_sb(Int_t sigma) const

 Get the expected Confidence Level for the background only
 if there is signal and background.

Double_t GetExpectedCLb_b(Int_t sigma) const

 Get the expected Confidence Level for the background only
 if there is only background.

Double_t GetAverageCLsb() const

Double_t GetAverageCLs() const

Double_t Get3sProbability() const

Double_t Get5sProbability() const
