This course provides an introduction to Econometrics. Econometrics applies economic theory and the tools of descriptive and inferential statistics to economic data to answer a wide variety of interesting questions. Econometrics theory and tools can be used to: describe the characteristics of a population; create hypotheses and test the predictions of a theoretical model; and estimate the statistical relationship between two variables. This course will introduce you to the theoretical foundations and empirical applications of multiple regression analysis. Because a key concern of modern econometric practice is the estimation of causal relationships between variables, the course will place special emphasis on threats to the validity of causal inferences. The course will also introduce you to STATA, a powerful and widely used statistical software package.
