HypoTestPlot()
Constructor.
Definition: HypoTestPlot.h:25
This class displays a legend box (TPaveText) containing several legend entries.
Definition: TLegend.h:23
void SetLineColor(Color_t color, const SamplingDistribution *samplDist=0)
Sets line color for given sampling distribution and fill color for the associated shaded TH1F...
const char Option_t
Definition: RtypesCore.h:64
void ApplyResult(HypoTestResult &result, Option_t *opt="NORMALIZE HIST")
Applies a HypoTestResult.
Definition: Rtypes.h:64
HypoTestResult is a base class for results from hypothesis tests.
Double_t AddSamplingDistribution(const SamplingDistribution *samplingDist, Option_t *drawOptions="NORMALIZE HIST")
adds the sampling distribution and returns the scale factor
This class provides the plots for the result of a study performed with any of the HypoTestCalculatorG...
Definition: HypoTestPlot.h:22
SamplingDistribution * GetAltDistribution(void) const
STL namespace.
void GetAbsoluteInterval(Double_t &theMin, Double_t &theMax, Double_t &theYMax) const
null_t< F > null()
Bool_t GetPValueIsRightTail(void) const
void SetLineWidth(Width_t lwidth, const SamplingDistribution *samplDist=0)
void ApplyDefaultStyle(void)
Set default style options (also called in the constructor that takes a HypoTestResult).
Double_t AddSamplingDistributionShaded(const SamplingDistribution *samplingDist, Double_t minShaded, Double_t maxShaded, Option_t *drawOptions="NORMALIZE HIST")
Like AddSamplingDistribution, but also sets a shaded area in the minShaded and maxShaded boundaries...
HypoTestResult * fHypoTestResult
Definition: HypoTestPlot.h:36
Double_t GetTestStatisticData(void) const
static Double_t infinity()
Return internal infinity representation.
Definition: RooNumber.cxx:49
SamplingDistribution * GetNullDistribution(void) const
This class simply holds a sampling distribution of some test statistic.
Namespace for the RooStats classes.
