26.2. Fitting examples#
Fits used in Belle II analyses can be simple or challenging. The examples listed below cover different levels of complexity and represent a good starting point for anybody interested to learn the basics of fitting:
For each example, fitting code has been developed within at least one of the following frameworks:
RooFit - the recommended framework included in ROOT
zfit - a python-based fitter
MINUIT - the basic tool upon which RooFit and zfit rely, can be useful if you want to have better control over the details of the fit
bat - the Bayesian Analysis Toolkit
Hydra - a framework for multithreaded data analysis
