Educational objectives
This course will introduce students to the most relevant statistical methods for business analysis.

In particular, theoretical lectures will be focused on the presentation of regression models for the analysis of economic and business data.

Specific attention will be also devoted to on empirical applications. Every week there will be a practical laboratory session in which students will apply concepts learned during the theoretical lectures, using statistical software.
Prerequisites
This course requires basic knowledge of descriptive and inferential statistics and probability theory.
