Chi2FCN class for binnned fits using the least square methods @ingroup FitMethodFunc
virtual void | SetNFitPoints(unsigned int n) const |
virtual double | DoDerivative(const double* x, unsigned int icoord) const |
virtual double | DoEval(const double* x) const |
effective points used in the fit (exclude the rejected one)
{ return fNEffPoints; }
set number of fit points (need to be called in const methods, make it const)
{ fNEffPoints = n; }
