Econ 8838 - Advanced Econometrics II (2nd-year Ph.D.)

Description: This is a second-year graduate econometrics course that focuses on the analysis of individual-level data. It covers econometric methods based on the general linear and nonlinear models for cross-section data and panel data. Numerical and simulation-based computational techniques in estimation will be explored. If time permits, spatial and social interaction models will be introduced. (course website)


Econ 8828 - Advanced Econometrics I (2nd-year Ph.D.)

Description:  Econ 8828 is an advanced level graduate econometrics course that focuses on asymptotic theory for cross-sectional data.  This course begins by reviewing the LS and IV estimators for linear models. Following this, the course provides large sample theory to study consistency, asymptotical normality, and asymptotical efficiency of the LS and IV estimators. If time permits, nonlinear estimators like quasi-ML and GMM estimators will be introduced. (course website)


Econ 7828 - Econometrics (1st-year Ph.D.)

Description: This is the second course of the first year graduate econometrics sequence. Built on the fundamental concepts in probability and statistics covered in ECON 7818, this course introduces linear and nonlinear regression models, and methods for estimation and inference. (course website)


Econ 4818 - Introduction to Econometrics (Undergraduate)

Description: This course provides an introduction to the theory and applications of modern econometrics. In this course, students are guided through the principals of simple and multiple regression analysis. Issues related to estimation, inference and specification will be explored. (course website)


Econ 3818 - Introduction to Statistics with Computer Applications (Undergraduate)

Description: This course gives an introduction to statistics with emphasis on both theory and applications. It covers basic statistical concepts and techniques, and introduces their applications to a variety of practical problems. (course website)
