Welcome to the RooStats Wiki

NEW Opportunity to contribute to RooFit/RooStats development

See the Opportunity listing on the LPCC homepage: http://lpcc.web.cern.ch/LPCC/index.php?page=misc

What is RooStats?

This is a wiki for RooStats development. RooStats is a project to create statistical tools built on top of RooFit and distributed in ROOT. It is a joint project between the LHC experiments and the ROOT team. There is an old users guide here. The latest version of the HistFactory documentation (draft 5, under development) is found here: CERN-OPEN-2012-016 and new C++ and Python bindings described here.

How to get it?

The current recommended version ships with ROOT 5.30. All you need is the latest ROOT release. The code is developing quickly, so you may need to Download and Install the RooStats Branch

Tutorial Screencasts on YouTube

In addition to the user's guide, we will be providing some screen casts. The first getting started screen guide is below. And more can be found at http://www.youtube.com/RooStats. You will want to choose the HD version to see more clearly.

Organization

The RooStats project has an oversight committee formed by the heads of the ATLAS and CMS statistics forums. Through several joint ATLAS-CMS statistics meetings we have converged on a structure in which the oversight committee sets goals and priorities for tool development (at a high level), adjudicates any conflicts that might arise, and helps find manpower if needed. The development of RooStats is open in nature, with four core developers:

• Kyle Cranmer representing ATLAS
• Gregory Schott representing CMS
• Lorenzo Moneta representing ROOT
• Wouter Verkerke representing RooFit (on which RooStats is based)

These core developers have access to ROOT's SVN repository.

Benchmark workspaces and likelihoods

In the ongoing discussion of publishing likelihood functions, we are collecting some benchmark workspaces representing hypothetical measurements, searches, etc. from the LHC.
