Function documentation

HypoTestCalculatorGeneric(const RooAbsData& data, const RooStats::ModelConfig& altModel, const RooStats::ModelConfig& nullModel, RooStats::TestStatSampler* sampler = 0)

HypoTestResult* GetHypoTest() const

 inherited methods from HypoTestCalculator interface

void SetNullModel(const RooStats::ModelConfig& nullModel)

 set the model for the null hypothesis (only B)

{ fNullModel = &nullModel; }

const RooAbsData * GetData(void)

{ return fData; }

const ModelConfig* GetNullModel(void)

{ return fNullModel; }

const RooArgSet* GetFitInfo() const

 set the model for the alternate hypothesis  (S+B)

{ return NULL; }

void SetAlternateModel(const RooStats::ModelConfig& altModel)

{ fAltModel = &altModel; }

const ModelConfig* GetAlternateModel(void)

 Set the DataSet

{ return fAltModel; }

void SetData(RooAbsData& data)

{ fData = &data; }

TestStatSampler* GetTestStatSampler(void)

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

{ return fTestStatSampler; }

void UseSameAltToys()

 set this for re-using always the same toys for alternate hypothesis in
 case of calls at dofferent null parameter points
 This is useful to get more stable bands when running the HypoTest inversion

int CheckHook(void)

 should return zero (to be used later for conditional flow)

{ return 0; }

int PreNullHook(RooArgSet* , double ) const

{ return 0; }

int PreAltHook(RooArgSet* , double ) const

{ return 0; }

void PreHook() const

{ }

void PostHook() const

{ }

void SetupSampler(const RooStats::ModelConfig& model) const

void SetAdaptiveLimits(Double_t obsTestStat, Bool_t forNull) const

SamplingDistribution* GenerateSamplingDistribution(RooStats::ModelConfig* thisModel, double obsTestStat, RooAbsPdf* impDens = __null, const RooArgSet* impSnapshot = __null) const
