Likelihood and minimization: setting up a chi^2 fit to a binned dataset
{
std::unique_ptr<RooDataSet>
d{model.generate(
x, 10000)};
std::unique_ptr<RooDataHist>
dh{
d->binnedClone()};
}
ROOT::Detail::TRangeCast< T, true > TRangeDynCast
TRangeDynCast is an adapter class that allows the typed iteration through a TCollection.
Efficient implementation of a sum of PDFs of the form.
RooArgList is a container object that can hold multiple RooAbsArg objects.
RooArgSet is a container object that can hold multiple RooAbsArg objects.
Chebychev polynomial p.d.f.
Container class to hold unbinned data.
RooFit::OwningPtr< RooDataHist > binnedClone(const char *newName=nullptr, const char *newTitle=nullptr) const
Return binned clone of this dataset.
Variable that can be changed from the outside.
RooCmdArg EventRange(Int_t nStart, Int_t nStop)
RooCmdArg PrintLevel(Int_t code)
The namespace RooFit contains mostly switches that change the behaviour of functions of PDFs (or othe...
