Summary and Setup

This is a new lesson built with The Carpentries Workbench.

This exercise uses Combine, the CMS statistical analysis and combination tool. Combine is built around ROOT, RooFit and RooStats. It provides a command-line interface to several common workflows used in HEP statistical analysis.

More information on Combine can be found in

• the Combine paper: CMS-CAT-23-001 / arXiv:2404.06614
• detailed user manual: Combine github pages

CMS users can use Combine as part of CMS software. But Combine was also recently released for public use (public use instructions).

Prerequisite

For this exercise, we will use a standalone version of Combine available in a Docker container.

Install the Combine container using

BASH

docker run --name combine -it gitlab-registry.cern.ch/cms-cloud/combine-standalone:v9.2.1

You can start the container using

BASH

docker start -i combine
