Prof Gary King

These are slides I display in class while teaching, as well as videos of my lectures. My strategy is to go through as much material as possible at each lecture, subject to the constraint that everyone follows what I'm doing. The speed at which I go is therefore dependent on the composition of each year's class and the questions that arise. As such, the slides below are not broken up into distinct weeks (I seem to go through roughly 15-20 pages in a weekly session lasting almost 2 hours, but issues and topics not represented here are covered most weeks). Separate PDF versions appear for teaching (i.e,. with pauses, etc.) and for (color) printing. R code is provided for each section. I update these slides almost continuously while I teach. I'd appreciate if you would contact me with any comments, corrections, or suggestions.
