RooMinuit Class Reference

RooMinuit is a wrapper class around TFitter/TMinuit that provides a seamless interface between the MINUIT functionality and the native RooFit interface.

RooMinuit can minimize any RooAbsReal function with respect to its parameters. Usual choices for minimization are RooNLLVar and RooChi2Var RooMinuit has methods corresponding to MINUIT functions like hesse(), migrad(), minos() etc. In each of these function calls the state of the MINUIT engine is synchronized with the state of the RooFit variables: any change in variables, change in the constant status etc is forwarded to MINUIT prior to execution of the MINUIT call. Afterwards the RooFit objects are resynchronized with the output state of MINUIT: changes parameter values, errors are propagated. Various methods are available to control verbosity, profiling, automatic PDF optimization.

Constructor & Destructor Documentation

◆ RooMinuit() [1/2]

RooMinuit::RooMinuit ( RooAbsReal function)

Construct MINUIT interface to given function.

Function can be anything, but is typically a -log(likelihood) implemented by RooNLLVar or a chi^2 (implemented by RooChi2Var). Other frequent use cases are a RooAddition of a RooNLLVar plus a penalty or constraint term. This class propagates all RooFit information (floating parameters, their values and errors) to MINUIT before each MINUIT call and propagates all MINUIT information back to the RooFit object at the end of each call (updated parameter values, their (asymmetric errors) etc. The default MINUIT error level for HESSE and MINOS error analysis is taken from the defaultErrorLevel() value of the input function.
