Statistics for Economics and Business
The goal of this course is to familiarize students with regression models and achieve the following learning objectives: - Apply the theory of least squares to solve linear regression problems. - Use diagnostic techniques to determine whether a regression model fits a given dataset properly. - Implement regression models using statistical software R. - Conduct an analysis of the temporal properties of a statistical series.

Learning activities and methodology
The course is organized in theoretical classes, whose materials are slides, exercise classes and computer classes, where R will be used in order to illustrate and consolidate the contents.
