First Period
###### Course Type
Supplementary
Prerequisites. No formal prerequisite is set; nevertheless, the frequency of a basic

course in statistics is suggested in order to properly follow the lectures.

##### Objectives
Knowledge and understanding: knowledge and understanding of

univariate and multivariate descriptive statistics and of how to

summarize and visualize data, of the basics in inferential statistics, of the

fundamental elements of statistical modelling, of the basic concepts of

statistical learning, focusing on regression models and multivariate data

analysis techniques, and understanding of at least one statistical

software for data analysis and statistical learning applications.

Applying knowledge and understanding: understanding of statistical

methods as useful instruments for research in economics and social

sciences, ability to use descriptive and inferential statistics in order to summarize information, to analyze and interpret relationships between

variables and to test hypotheses, ability to use at least one statistical

software in order to develop simple data analysis.

Making judgements: making judgements on the appropriate statistical

models and methods to be used for analyzing a specific dataset and on

the interpretation of the experimental results.

Communication skills: communication skills in order to present a

statistical analysis, including both the methodology and the final

conclusions, in a consistent and convincing way.

Learning skills: learning skills based on the prerequisites that are

required for understanding autonomously a report with a statistical

analysis and for learning more advanced statistical procedures.

##### Contents
The course focuses on statistical methods for data analysis. The aim is to

introduce the fundamental elements of statistical modelling and the basic

concepts of statistical learning, with particular attention to regression

models and multivariate data analysis techniques. These notions will be

presented from an applied point of view and part of the course will take

place in the computer lab, using the R statistical software.
