TBinomialEfficiencyFitter

Binomial Fitter for the division of two histograms.
Use when you need to calculate a selection's efficiency from two
 histograms, one containing all entries, and one containing the subset
of these entries that pass the selection

Function documentation

TBinomialEfficiencyFitter(const TBinomialEfficiencyFitter& )
 default constructor
TBinomialEfficiencyFitter(const TH1* numerator, const TH1* denominator)
 Constructor
~TBinomialEfficiencyFitter()
 destructor
void Set(const TH1* numerator, const TH1* denominator)
 Initialize with a new set of inputs.
TVirtualFitter* GetFitter()
 static: Provide access to the underlying fitter object
Int_t Fit(TF1* f1, Option_t* option = "")
 Carry out the fit of the given function to the given histograms.

 If option "I" is used, the fit function will be averaged over the
 bin (the default is to evaluate it simply at the bin center).

 If option "R" is used, the fit range will be taken from the fit
 function (the default is to use the entire histogram).

 Note that all parameter values, limits, and step sizes are copied
 from the input fit function f1(so they should be set before calling
 this method).
 In output f1 contains the fitted parameters and errors
void ComputeFCN(Int_t& npar, Double_t* , Double_t& f, Double_t* par, Int_t flag)
 Compute the likelihood.
