The aim of the course is to make the students able to coherently use some statistical techniques for the analysis of multivariate data. The procedures covered in the course include:

- Introduction to multivariate analysis
- Multiple regression;
- Chi-square test
- T-test
- Principal components analysis
- Factor analysis.

## Course contents

1. Introduction to multivariate statistical analysis.
2. Multiple linear regression: model specification, parameters estimation, residual analysis.
3. Chi square test for independence
4. T-test to compare means
5. Principal components analysis.

## Teaching methods

- Lectures, during which theoretical concepts as well as statistical techniques are explained and illustrated by examples.
- Tutorial sessions in computer laboratory.

## Assessment methods

Depending on the sanitary provisions, the methods of examination may vary.
Written test (mandatory) and oral examination (optional).

"Covid" assessment:
You can choose between two alternatives:
- Teamwork (max 3 people): the team is given a series of problems to solve. Within the estabilished time, the team will have to return a document containing the required analyzes and comments.
The team can also be composed by one candidate and will obviously be proportionate.
- Online test: each candidate carries out a multiple choice test on the EOL platform. 20 questions in 45 minutes.

In both cases an oral test will follow.

Point system:
<18 not sufficient
18-23 sufficient
24-27 good
28-30 very good
30 e lode excellent
