Evaluate()

virtual Double_t RooStats::TestStatistic::Evaluate ( RooAbsData &  data, RooArgSet &  nullPOI  )

pure virtual

Main interface to evaluate the test statistic on a dataset given the values for the Null Parameters Of Interest.

Implemented in RooStats::DebuggingTestStat, RooStats::MaxLikelihoodEstimateTestStat, RooStats::NumEventsTestStat, RooStats::RatioOfProfiledLikelihoodsTestStat, RooStats::SimpleLikelihoodRatioTestStat, RooStats::MinNLLTestStat, and RooStats::ProfileLikelihoodTestStat.

GetDetailedOutput()

virtual const RooArgSet * RooStats::TestStatistic::GetDetailedOutput ( void  ) const

inlinevirtual

return detailed output: for fits this can be pulls, processing time, ... The returned pointer will not loose validity until another call to Evaluate.

Reimplemented in RooStats::MinNLLTestStat, RooStats::ProfileLikelihoodTestStat, RooStats::RatioOfProfiledLikelihoodsTestStat, and RooStats::SimpleLikelihoodRatioTestStat.

Definition at line 48 of file TestStatistic.h.

GetVarName()

virtual const TString RooStats::TestStatistic::GetVarName ( ) const

pure virtual

Implemented in RooStats::MaxLikelihoodEstimateTestStat, RooStats::MinNLLTestStat, RooStats::NumEventsTestStat, RooStats::ProfileLikelihoodTestStat, RooStats::RatioOfProfiledLikelihoodsTestStat, and RooStats::SimpleLikelihoodRatioTestStat.

PValueIsRightTail()

virtual bool RooStats::TestStatistic::PValueIsRightTail ( void  ) const

inlinevirtual

Defines the sign convention of the test statistic. Overwrite function if necessary.

Definition at line 45 of file TestStatistic.h.

SetConditionalObservables()

virtual void RooStats::TestStatistic::SetConditionalObservables ( const RooArgSet &  )

inlinevirtual

interface to set conditional observables. If a test statistics needs them it will re-implement this function

Reimplemented in RooStats::MaxLikelihoodEstimateTestStat, RooStats::ProfileLikelihoodTestStat, RooStats::RatioOfProfiledLikelihoodsTestStat, and RooStats::SimpleLikelihoodRatioTestStat.

Definition at line 51 of file TestStatistic.h.

SetGlobalObservables()

virtual void RooStats::TestStatistic::SetGlobalObservables ( const RooArgSet &  )
