This course brings together the tools of economic theory, mathematics, and statistical inference and applies it to the analysis of economic phenomena. It focuses on cross-sectional data analysis with a primary focus on linear regression. The course starts with the introduction of the classical linear regression model with emphasis on the ordinary least squares estimator and its properties and then moves on to the testing of hypotheses about the parameters in the classical linear regression model, large sample properties of estimators and test statistics, model selection and Binary dependent variable regression analyses. Students in the course will use the statistical software Stata to address real-world economic questions using nationally representative datasets to test economic theories and learn to determine the validity of the tests.
