StatTutorial

Welcome! In this tutorial, you will learn about a few of the statistical techniques that are essential in analyzing the data obtained from the proton-proton collision experiments.

The tutorial covers a wide range of topics, including likelihood fits, significances, exclusion limits and many more. You will be introduced to the basic concepts of each topic and provided with step-by-step instructions on how to actually perform the analysis using the ROOT software package.

The aim of this tutorial is to equip you with the necessary skills to analyze proton-proton collision data with confidence. So, let's get started!

Setup Instructions

This document will guide you through the process of setting up the environment needed to run the Statistics Tutorial based on the ROOT framework.

Prerequisites

  • Access to a terminal/command line interface.
  • Git installed on your machine. If not, you can download it from here.
  • ROOT installed. You can download it from here.

Optional but recommended: - A modern IDE (Integrated Development Environment) that supports C++ VS Code

Remote setup

  • In case you can not setup ROOT on your local machine, you can use a remote machine. For the Terascale Statistics school you can use ssh to connect. 
ssh -Y schoolXX@naf-school.desy.de

with XX=[00,80]. Keep your number in mind, and use this today and tomorrow.

The password will be provided during the school.

Clone the Repository

First, clone the GitLab repository by running the following command in your terminal:

git clone https://gitlab.cern.ch/AnalysisWalkThrough/StatTutorial.git

To setup the right plot styles a rootlogon file can be setup using:

source setup.sh

Optional in case ROOT can not be installed: Setup Docker and load the Docker image

If you do not have Docker installed, you can find installation instructions here.

If you have Docker installed, you can run the following command from the root of the repository to get a terminal with the code of this repo and ROOT installed.

docker run -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix --mount type=bind,source="$(pwd)",target=/opt/StatTutorial --rm -it --user $(id -u) rootproject/root:latest /bin/bash

The -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix can be used on linux to enable graphical forwarding through the docker container. Fow windows and osx devices, see the enabling graphics section in https://hub.docker.com/r/rootproject/root.
