This section discusses the specific tools for recommended for building valid and robust statistical models. The RooFit pacakge is core to data modeling in ROOT.
We begin with a discussion of the RooFit philosophy - we want a single language for all measurements: common tools & joint model building (other tools) followed by a description of the RooFit language basics, and the workspace. A series of tools for building & manipulating models built using RooFit as a foundation are described with some links and general usage. Finally a list of good practices are presented regarding issues such as modeling systematics, uncertainties, and model cleaning among others.
