Higgs analysis at ATLAS using RooStats

This page contains basic information on getting started with Higgs analysis at ATLAS using RooStats. The information will be updated in due course.

What is RooStats?

RooStats is a project to create statistical tools built on top of the RooFit library (a data modeling toolkit). It is distributed in ROOT. Specifically, it has been distributed in the ROOT release since version 5.22 (December 2008). The latest release of ROOT is dev. version 5.27/06. To use RooStats, a version of ROOT greater than 5.22 is required. The latest version of ROOT is recommended as the RooStats project is developing quickly.

How do I get RooStats?

There are three options:

Option 1: Download the latest ROOT release.

Do this if you want to install ROOT from binaries.
