RooStats::FeldmanCousins

Function documentation

FeldmanCousins(RooAbsData& data, RooStats::ModelConfig& model)

     FeldmanCousins();
 Common constructor

virtual ~FeldmanCousins()

PointSetInterval* GetInterval() const

 Main interface to get a ConfInterval (will be a PointSetInterval)

Double_t Size() const

 Get the size of the test (eg. rate of Type I error)

{return fSize;}

Double_t ConfidenceLevel() const

 Get the Confidence level for the test

{return 1.-fSize;}

void SetData(RooAbsData& )

 Set the DataSet

void SetPdf(RooAbsPdf& )

 Set the Pdf

void SetParameters(const RooArgSet& )

 specify the parameters of interest in the interval

void SetNuisanceParameters(const RooArgSet& )

 specify the nuisance parameters (eg. the rest of the parameters)

void SetParameterPointsToTest(RooAbsData& pointsToTest)

 User-defined set of points to test

void SetPOIPointsToTest(RooAbsData& poiToTest)

 User-defined set of points to test

void SetTestSize(Double_t size)

 set the size of the test (rate of Type I error) ( Eg. 0.05 for a 95% Confidence Interval)

{fSize = size;}

void SetConfidenceLevel(Double_t cl)

 set the confidence level for the interval (eg. 0.95 for a 95% Confidence Interval)

{fSize = 1.-cl;}

void SetModel(const RooStats::ModelConfig& )

RooAbsData* GetPointsToScan()

ConfidenceBelt* GetConfidenceBelt()

{return fConfBelt;}

void UseAdaptiveSampling(bool flag = true)

{fAdaptiveSampling=flag;}

void AdditionalNToysFactor(double fact)

{fAdditionalNToysFactor = fact;}

void SetNBins(Int_t bins)

{fNbins = bins;}

void FluctuateNumDataEntries(bool flag = true)

{fFluctuateData = flag;}

void SaveBeltToFile(bool flag = true)

void CreateConfBelt(bool flag = true)

{fCreateBelt = flag;}

TestStatSampler* GetTestStatSampler() const

 Returns instance of TestStatSampler. Use to change properties of
 TestStatSampler, e.g. GetTestStatSampler.SetTestSize(Double_t size);

void CreateParameterPoints() const

 initializes fPointsToTest data member (mutable)

void CreateTestStatSampler() const

 initializes fTestStatSampler data member (mutable)
