- This course is an introduction to the theory and application of statistics to economic problems. This course focuses on the techniques used in empirical research with a particular focus on intuitive understanding. Weekly problem sets will introduce real world applications and teach you the fundamentals of statistical programming. No prior knowledge of computer programming is required. Class meets three times a week for lectures which are mandatory, and once per week for section which are strongly suggested though not mandatory. You are expected to maintain the standards of academic integrity delineated here. Any violations of academic integrity standards will be dealt with in accordance with University policy.
