Class Econometrics I

The main objective of this course is to provide students with introductory knowledge of some of the main econometric techniques used in the analysis of linear economic relationships using cross-sectional data. The aim is for students to master not only the theoretical aspects of these techniques, but also to know how to apply them critically to the concrete analysis of economic problems using real data. Additional objectives include strengthening the ability to incorporate the postulates of economic theory into mathematical and statistical models for quantification, learning the methods and techniques of linear regression analysis from the dual perspective of estimation and inference, and, as far as possible, becoming accustomed to the use of computer tools that support the production of econometric analyses.
