 iminuit is a Jupyter-friendly Python interface for the Minuit2 C++ library
 maintained by CERN's ROOT team.
 
 It can be used as a general robust function minimisation method, but is most
 commonly used for likelihood fits of models to data, and to get model parameter
 error estimates from likelihood profile analysis.
