Function documentation

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

 Constructor. When test stat sampler is not provided
 uses ToyMCSampler and RatioOfProfiledLikelihoodsTestStat
 and nToys = 1000.
 User can : GetTestStatSampler()->SetNToys( # )

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

 common setup for both models

~HypoTestCalculatorGeneric()

HypoTestResult* GetHypoTest() const

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

void SetNullModel(const RooStats::ModelConfig& nullModel)

 set the model for the null hypothesis (only B)

{ fNullModel = &nullModel; }

const ModelConfig* GetNullModel(void)

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

{ return fNullModel; }

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; }

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 SetAdaptiveLimits(Double_t obsTestStat, Bool_t forNull) const

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