Lesson45 Analysis of Covariance

A logical extension of ANOVA and regression is ANCOVA, or Analysis of Covariance. Two general applications are described, one where we can attain power to detect treatment effects by including a continuous covariate in the model, and one where we are actually interested in the 2nd (or higher) order interaction between a continuous and nominal variable.

Thank you for a clear presentation about this topic. It was a useful review that helped me remember what ANCOVA was and how to word it for a proposal's statistical analysis section.
