ECTS 9

Description
The objective of the course is to provide students with a thorough coverage of the classical econometric theory and with the computational tools to be
used in the empirical analyses. The program varies with the students background, but generally includes the following topics: the classical
regression model, relaxing the assumptions of the classical model, time series econometrics and simultaneous equation models.
