EC 421, Spring 2020
Welcome to Economics 421: Introduction to Econometrics (Spring 2020) at the University of Oregon (taught by Edward Rubin).
For information on the course specifics, please see the syllabus.
Lecture slides
The slides below (linked by their topic) are .html files that will only work properly if you are connected to the internet. If you're going off grid, grab the PDFs (you'll miss out on gifs and interactive plots, but the equations will render correctly). I create the slides with xaringan in R. Thanks go to Grant McDermott for helping/pushing me to get going with xaringan.
