Prerequisites:

The knowledge of Basic Data Science Techniques is requested.

Objectives

The training aim for the student is to reach the following learning outcomes:

Knowledge and ability to understand

The course aims to provide methodological and application advances of specific data science methods. In particular, students will analyze some types of economic and business data through specific statistical techniques. We also want to encourage students to specialize in the use of the open source statistical package R.

Ability to apply knowledge and understanding

At the end of the teaching course, the student will also be able to analyze data bases, even large ones, with sophisticated statistical methods, with the help of case studies carried out with the statistical software R. The acquired knowledge will allow him to critically interpret economic and / or business relationships.

Evaluation methods

Verification of learning:

Knowledge and ability to understand

To verify the learning a test and an interview are scheduled. The test will consist of theoretical questions and empirical exercises on the whole program with particular attention to the use of the software R, simulating some statistical analysis on real case studies. The final evaluation, expressed in thirtieths, takes into account both the test and the interview.

Ability to apply knowledge and understanding

During the test and the interview, students' ability to apply the knowledge of advanced data science models is tested so as to be able to deal with specific case studies.
