20630 Introduction to Sport Analytics
This course provides the analytics requirements of a Sports Management program. It is also an opportunity for applied work for all students interested in Data Science. All applications in the course will be based on the statistical software R. The course is taught through a combination of lectures, class discussion, group presentations. Students are required to read assignments from the texts as well as additional sources provided by the instructor. Students must attend class prepared to engage in discussions; have, articulate and defend a point of view; and ask questions and provide comments based on their reading and on their own R applications.
Projects will be allocated to groups of attending students. Project reports and their presentation will be part of the evaluation for attending students.
Presentations on the use of analytics in the Sport Business:
Using Analytics for a Euroleague Basketball Team, presentation by Mario Fioretti, Assistant Coach, Olimpia Milano
Using Analytics in the European Soccer Industry, presentation by Mark Nervegna, Head of Strategy and Analytics, Raiola Global
Pre-Requisites: Students are expected to have attended a core course in statistics and to be familiar with basic calculus and linear algebra.
Teaching Assistant: Office Hours will be held online viaTeams, the Teaching Assistant will follow students both on projects and on exercises

Project 1: Getting sport data from the web with R
The objective of this project is to illustrate how data on sports could be efficiently retrieved from the Web (via API and/or webscraping). Students should feel free to choose their preferred field and application.
Accessing APIs from R a tutorial , an R code for the tutorial, Accessing data from Github using an R code
Project 2: Creating Web Applications with Rshiny
The objective of this project is to create a Sport related web application with RShiny. An Illustration based on NBA data is provided together with projects produced in 2020. Students should feel free to choose their preferred field and application.

Project 3: An Application of Unsupervised Machine Learning to Sport Analytics
The objective of this project is to apply unsupervised machine learning, and in particular cluster analysis, to finding groups in Sport Analytics data.

Project 4: An Application of Supervised Machine Learning to Sport Analytics
The objective of this project is to apply supervised machine learning techniques , and in particular techniques to solve the many predictor problem to predict top athletes compensations.
Students should use as a benchmark the model presented in the lectures and evaluate it against alternatives generated by modern machine learning techniques.
A further possibility for a group undertaking this project is the costruction of a data challenge related to the topic of the project using the data challenge website of Bocconi University.

Project 5: Evaluating the Home Advantage Effect from quasi-Natural Experiments
Following the COVID shock many games in many sport were played without attendance within "bubbles" in which no team had the "home advantage effect". The objective of this project is to use sport data to construct a quasi-natural experiment for the evaluation of the Home Advantage Effect.

Project 6: Measuring Competitive Advantage and its effects
The objective of this project is to introduce, discuss the concept of Competitive Balance in the Sport Industry. Both a discussion of the theory and applications are possible.
