I am using default minimizer in my 3 Gaussian roofit.
I see a reasonable fit by looking at the chi^2 value.
But I do not know what does status = 6 means.
Could you please help me to understand better?
RooFitResult* res = sum.fitTo(dh0,
where “sum” is RooAddPdf of 3 Gaussian.
Double_t chi20 = frame0->chiSquare(“sum”, “dh0”, 9);
status is computed as: res->status()
