WebRooFit is a library of C++ classes that facilitate data modeling in the ROOT environment. Mathematical concepts such as variables, (probability density) functions and integrals are … WebRooWorkspaces are a method of persistifying RooFit and RooStats objects. The basic apparoach to creating them is to import into it RooFit objects, such as pdf, datasets and variables. Datasets can be of any RooAbsData types. This allows for large range of flexibility. WebOften, they might be constrained because external knowledge about them exists, e.g. from external measurements. Constraint parameters No direct use in RooFit/RooStats. Can be used by the user for bookkeeping. Observables Parameters that have been measured externally, i.e. they exist in a dataset. g force effects

WebThe original class structure of RooFit featured an abstract dataset class RooAbsData. Inheriting from that was a single class RooTreeData, which implemented datasets with a ROOT TTree -based storage implementation, and inheriting from that two classes RooDataSet , representing unbinned data, and RooDataHist, representing binned data. christoph strempflWebRooFit users tutorial Projecting out dimensions Projection via Integration Projecting discrete vs real observables Projection via data averaging Mixing projection methods.
