Hi Cynthia, see example in TH1::Fit that calls TFitter::GetStats with: Int_t TFitter::GetStats(Double_t &amin, Double_t &edm, Double_t &errdef, Int_t &nvpar, Int_t &nparx) { // return global fit parameters // amin : chisquare // edm : estimated distance to minimum // errdef // nvpar : number of variable parameters // nparx : total number of parameters Int_t ierr = 0; gMinuit->mnstat(amin,edm,errdef,nvpar,nparx,ierr); Rene Brun On Wed, 11 Sep 2002, Hadjidakis Cynthia wrote: > > Hi Rooters, > > I'm using TMinuit for fitting histograms.
