Lecture 2 is now available on the CLE. Note, this lecture was recorded in smaller chunks - please be sure to watch lecture 2, parts 1-3, as well as the lecture 2 stata demo.
Also, I noticed a small glitch around the 15-minute mark of part 1 and another at the end of part 3. Rest assured, there is no content missing.
Finally, if you have any outstanding questions on lecture 1 material or homework 1, please join us for office hours this Friday (7/23) from 8:30-10AM PST (Zoom link on course CLE).
