Obiettivi

Tukey (1962) defines Data Analysis to be “Procedures for analyzing data, techniques for interpreting the results of such procedures, ways of planning the gathering of data to make its analysis easier, more precise or more accurate, and all the machinery and results of (mathematical) statistics which apply to analyzing data.”

The goal of this course is 

  1. to provide the students with the thinking framework for data analysis
  2. equip them with tools and resources to obtain and manage financial data.
  3. to foster creativity in using and exploring existing datasets as well as in creating new datasets
  4. to equip students with techniques to visually communicate their results

Impostazione pedagogico-didattica

This course will take students from theory to practice in four steps. Students prepare with reading a short text or watching a video. Then new topics are introduced in a lecture, which is followed by learning-by-doing laptop session. Students finally apply their new knowledge in individual homeworks, which are collected and presented in a student portfolio.

Programming is heavily centred around AI tools, using Github Copilot. Based on these AI tools, several programming languages  will be used throughout the course: the R and Python languages, a bit of SQL and bash (Linux) as well as Tableau (free student version). 

Students are free to use any language or tool for the assignments. Students are required to bring a laptop to every class. Students will also need a ChatGPT Plus licese for the second part of the course. Occasionally, we will work with LINUX. Student can access a server made available by the lecturer or continue to use their server from Programming in Finance and Economics II.

Modalità d’esame

40% – Written midterm exam
60% – Portfolio
Students create an individual portfolio of ca. 20 pages from their work throughout the semester, including

  • One discussion of data sets and/or methods
  • One discussion of a paper from the literature
  • Several data visualizations
