Modeling Clustered and Longitudinal Data - resources from Don Hedeker

Don Hedeker taught a tremendously useful, informative, and enjoyable course on multilevel modeling for clustered and longitudinal data at the recent Deming Conference. He managed to cover underlying theory (with a light touch), difficulties with approaches that ignore the structure of the data, and the multilevel approach to modeling. He illustrated every concept with practical applications using real data. He told jokes. He included funny New Yorker comics. It was a blast!

Presentation slides are posted on his web site (see under "Links"). He has also posted datasets and SAS code that he used to demonstrate his points. This is such a valuable collection of resources that I wanted to include specific pointers:
- Introduction to Multilevel Modeling. The slides posted here are the ones he used at the short course.

- Longitudinal data - continuous, binary, ordinal. These are the materials that he used in the course. His inclusion of missing data issues and strategies is important and quite useful.

I don't know if he will be teaching this course anywhere soon, but I highly recommend it!
