Objectives

The course of data science in economics aims to contribute to the student's learning process by providing methodologies for quantitative analyses that are useful for economic and business decisions.
In particular, these learning objectives can be associated with the following expected learning outcomes:

Knowledge and understanding
The course aims to provide the basic methodological and application knowledge of data science. Furthermore, we want to provide useful tools for the statistical analysis of certain types of economic and business data. Finally, great attention will be given to the open source statistical package R.

Applying knowledge and understanding
At the end of the course, the student will also be able to analyze data- bases, including large ones, with modern statistical techniques, with the help of case studies carried out with the statistical software R. The acquired knowledge will allow him/her to critically interpret the economic and / or business dynamics.

Verification of learning:

Knowledge and understanding
The verification of the learning outcomes will be carried out through a written and oral examination. The written exam will cover the whole program with particular attention to the use of R software. Students will also have to prepare and discuss some statistical analyses, carried out with R, concerning real case studies (data sets can be found on the internet ). These documents must be sent to the Professor at least one week before the exam date.
The score of the exam is assigned by a vote expressed in 30.

Applying knowledge and understanding
During the exam and the development of the applied work, students' ability to apply the knowledge of data science models is verified to be able to face concrete analysis situations.
