Function documentation

TConfidenceLevel(const TConfidenceLevel& )
 Default constructor
TConfidenceLevel(Int_t mc, bool onesided = kTRUE)
 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 = 0) const
 Get the expected statistic value in the background only hypothesis
Double_t GetExpectedStatistic_sb(Int_t sigma = 0) const
 Get the expected statistic value in the signal plus background hypothesis
Double_t CLb(bool use_sMC = kFALSE) const
 Get the Confidence Level for the background only
Double_t CLsb(bool use_sMC = kFALSE) const
 Get the Confidence Level for the signal plus background hypothesis
Double_t CLs(bool use_sMC = kFALSE) 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 = 0) const
 Get the expected Confidence Level for the signal plus background hypothesis
 if there is only background.
Double_t GetExpectedCLb_sb(Int_t sigma = 0) const
 Get the expected Confidence Level for the background only
 if there is signal and background.
Double_t GetExpectedCLb_b(Int_t sigma = 0) const
 Get the expected Confidence Level for the background only
 if there is only background.
Double_t GetAverageCLsb()
 Get average CLsb.
Double_t GetAverageCLs()
 Get average CLs.
Double_t Get3sProbability()
 Get 3s probability.
Double_t Get5sProbability()
 Get 5s probability.
void Draw(Option_t* option = "")
 Display sort of a "canonical" -2lnQ plot.
 This results in a plot with 2 elements:
 - The histogram of -2lnQ for background hypothesis (full)
 - The histogram of -2lnQ for signal and background hypothesis (dashed)
 The 2 histograms are respectively named b_hist and sb_hist.
void SetTSB(Double_t* in)
 Set the TSB.
void SetTSS(Double_t* in)
 Set the TSS.

{ fTSD = in; }
void SetLRS(Double_t* in)
{ fLRS = in; }
void SetLRB(Double_t* in)

{ fStot = in; }
void SetDtot(Int_t in)
{ fDtot = in; }
Double_t GetStatistic()
{ return -2 * (fTSD - fStot); }
Double_t GetExpectedCLs_b(Int_t sigma = 0) const
{ return (GetExpectedCLsb_b(sigma) / GetExpectedCLb_b(sigma)); }
Int_t GetDtot()
{ return fDtot; }
Double_t GetStot()
{ return fStot; }
Double_t GetBtot()
