Theoretical Econometrics will introduce students to the theoretical reasoning underpinning regression analysis as covered in ECON 0211. The course will begin with regression analysis as a method of data summary, focusing on geometric properties that hold for all data sets. We will introduce progressively the assumptions of the classical linear regression model to provide clear relationships between probabilistic assumptions and statistical properties and the arguments that justify them. We will conclude by exploring generalizations to basic regression that are motivated by violations of the classical assumptions. Throughout the course, students will encounter the interaction between economic and econometric modeling. (ECON 0211) 3 hrs. lect.
