Function Documentation

ClassImp

(

TBackCompFitter

)

Backward compatible implementation of TVirtualFitter using the the class ROOT::Fit::Fitter. This class is created after fitting an histogram (TH1), TGraph or TTree and provides in addition to the methods of the TVirtualFitter hooks to access the fit result class (ROOT::Fit::FitResult), the fit configuration (ROOT::Fit::FitConfig) or the fit data (ROOT::Fit::FitData) using

   TBackCompFitter * fitter = (TBackCompFitter *) TVirtualFitter::GetFitter();
   ROOT::Fit::FitResult & result = fitter->GetFitResult();
   result.Print(std::cout);
   

Methods for getting the confidence level or contours are also provided. Note that after a new calls to TH1::Fit (or similar) the class will be deleted and all reference to the FitResult, FitConfig or minimizer will be invalid. One could eventually copying the class before issuing a new fit to avoid deleting this information

void InteractiveFCNm2	(	Int_t &	npar,
		Double_t *	gin,
		Double_t &	f,
		Double_t *	u,
		Int_t	flag
