I am fitting data histogram with a composite function to evaluate the signal and background contributions. RooRealVar coeffModel("coeffModel", "coeffModel", 0., 0., 1.); RooAddPdf sumModel("sumModel", "coeff*modelPdf1 + (1 - coeff)*modelPdf2", model_mc0Temp, model_mc1Temp, coeffModel);
If I fit a sub-range of the distribution, in that case returned value of fraction “coeffModel” will be only in this sub-range or this will correspond to full range fraction?
If this fraction corresponds to sub-range, how I can translate this into corresponding value of fraction in full range?
If I do similar study using TFraction Fitter, evaluation of fraction by fitting sub-range i.e. fit->SetRangeX(0,rMax);
What will be the corresponding fraction value, it will be w,r.t. sub-range events or full range?
Many thanks for your feedback!
