The Toolkit for Data Modeling with ROOT allows for modeling probability distributions in a compact and abstract way.


What RooFit can do for you

  • Intuitive, interactive, physics-based, statistical model building
  • Handles all the numerical computations necessary for parameter estimation behind the scenes
  • Automatically optimizes calculations for faster results
  • Used by many large particle physics experiments

RooFit is a staple tool of particle physics analysis. Developed over the past two decades, mainly by Wouter Verkerke, it has grown into a widely used statistical modeling and parameter estimation package.
