Here are my current/recent teaching materials, including course materials and other material potentially of interest to aspiring statisticians. Courses from my past include Biostatistics I, a more-or-less introductory level applied biostatistics course aimed at graduate students in the health sciences at the University of Calgary. Biostatistics II, is follow-up course covering generalized linear models. Lastly there are compact PDF-versions of standard statistical tables.
My collection of Sample Size Calculators provides a set of simple-to-use JavaScript utilities for doing basic sample size calculations. I also provide some resources for calculating model-adjusted survival curves, in particular an S function and SAS code for direct standardization (aka the "corrected group prognosis" approach).
While I've got your attention, I'll take the opportunity to share some of my statistical pet peeves, in particular regarding stepwise regression, post hoc power calculations and interpetation of statistical models. Much to the chagrine of the statistical community, stepwise regression remains the most widely followed approach to model selection in multiple regression. The FAQ section of STATA's web-site provides a very helpful discussion titled Problems with Stepwise Regression, with insightful comments from Frank Harrell and Ronan Conroy. A helpful introduction to alternate approaches can be found in the paper Suggestions for presenting the results of data analyses by Anderson, David R., William A. Link, Douglas H. Johnson, and Kenneth P. Burnham.Post-hoc power calculations are usually conducted to help inform the interpretation of non-significant results. Confidence intervals provide a more sound and simpler approach. The advice section of Russ Lenth's power and sample-size page provides expanded discussion of this and other issues, in particular rather scathing criticisms of the use of the "effect size" approach to sample size calculation.
Lastly there's the issue of model interpretation. Many statistical models, such as proportional hazards models and logistic regression models are parameterized in such a way that model parameters are not directly interpretable. For example, it's hard to explain what an odds ratio really means (beyond the mathematical formula), unless one is dealing with rare outcomes, in which case they approximate the more easily understood relative risk.
I've helped author a couple of papers on the topic, but I've recently come across the efforts of a group of Harvard researchers who've made a concerted attempt to provide a general framework for doing this. Implementations of there idea exist in STATA (the Clarify program) and in R (the Selig package). Please visit Imai, Kosuke, Gary King and Olivia Lau. 2005.
