What I do
I'm retired after 38 years of working for the University of Michigan, mainly at the Center for Statistical Consultation and Research, as a statistical consultant. I am currently co-teaching a course on the analysis of clustered and longitudinal data: Biostat 512 with Missy Plegue. I have designed and presented workshops on Introduction to SAS and Intermediate SAS , and Introduction to Proc Mixed for correlated and longitudinal data. I have also co-presented a workshop on Generalized Linear Models.

I am interested in models for correlated data for continuous outcomes, and generalized estimating equations (GEE) and other models for correlated discrete outcomes.
