Calculating R-squared for linear mixed effects models

Last week, we discussed the issue of choosing the best model versus evaluating how well that best model actually fits the data. Here is a blog post that discusses the issue in detail. It's not simple.

Welcome to Biology 864: Mixed-Effects Linear Models

Biology 864 is a graduate course that explores the use of mixed effects linear models in biology.  Feel free to check out the syllabus to see what the course is all about.
