The main textbook for the class is Andrew Gelman and Jennifer Hill (2007): Data Analysis Using Regression and Multilevel/Hierarchical Models. [GH]
We additionally use Greene (2003): Econometric Analysis, 5th edition [Greene] and Cameron and Trivedi (2005): Microeconometrics [CT].

Date Topic Reading in text Handout (if any) Exercise (if any) Data, syntax files, anything else of use
Week 1: 9/5 Introductory discussion - what do we want to learn? Beginning discussion of hierarchical modeling Review of single-level regression models. GH, Part 1A "Single-level regression"      
Week 2: 9/10 and 9/12 No classes. Install R and WinBUGS and learn how to use the software. To learn R: "An Introduction to R" available here. Look at Intro, Simple Manipulations, QUICKLY glance at (but do not master) Object and Factors, then do Arrays, Lists, Reading Data, Prob Dists, look at loops (you will do this later), skip writing own fns for now, then do some stats and graphs examples, then look at packages, make sure you can deal with a sample session and invoking R.

GH: Read and work the examples in 11 and 12. Once you are done with that, work the examples (and only work the examples) in 16 and 17 using Bugs.
