Hi,
Fit converges, but RooFit returns fit yields with “limited”. Is there any meaning to it? Is it because I am giving ranges to the fit parameters?
For example:
RooRealVar mean(“mean”, “mean of gaussian”, 5300, 4800, 5600);
RooRealVar sigma(“sigma”, “width of gaussian”, 5.7, 1, 50);
RooRealVar alphaL(“alphaL”, “left tail parameter”, 1.9, 0.1, 10.);
RooRealVar nL(“nL”, “left exponent”, 1.86, 0.1, 10.);
RooRealVar alphaR(“alphaR”, “right tail parameter”, 1.76, 0.1, 10.);
RooRealVar nR(“nR”, “right exponent”, 2.42, 0.5, 10.);
