90483 - MODERN STATISTICS AND BIG DATA ANALYTICS

Scheda insegnamento

Anno Accademico 2021/2022

Conoscenze e abilità da conseguire

By the end of the course, the student gains an understanding of theory and computing of modern statistical methods, with particular emphasis on methods for analysing large amounts of data (big data). More specifically, the student acquires knowledge on the most important methods of statistical learning and prediction and the skills required to solve real-world and decision-making problems.

Robust statistics: Influence function, breakdown point, robust estimation of univariate and multivariate location and scale and regression, with algorithms, R-coding, theory, applications and in-depth discussion

Modalità di verifica e valutazione dell'apprendimento

The assessment will have two components plus a bonus component. About 10/30 marks are assigned to a literature question to be done at home. These marks will be given for the ability to understand the scientific explanation of new methodology which is based on and closely related to methodology introduced in the course, the understanding of which is implicitly also assessed. About 20/30 marks are assigned to a 3 hours exam comprising of a theoretical exercise, a data analysis project, and an exercise that asks questions interpreting the given output of another data analysis. Aspects examined here are understanding of the theoretical background and how it is derived (carrying a rather low percentage of the marks), the ability to apply methodology learnt in the course to a real dataset, and the ability to understand and draw practically relevant conclusions from the computer output of such methodology.

5/30 bonus marks are assigned to regular homework activity (homework needs to be done but not necessarily correctly; students can work in groups if they choose to do so); they will count on top of the marks achieved in the written exam and the literature question as long as these are below 30. A 30L is achieved by either having at least 31 marks including homework bonus, or by having all 30 marks in literature question and exam alone.
