Learn how to work with random and fixed effects using LMM and GLMM!
Mixed effects models allow ecologists to overcome a number of limitations associated with traditional linear models.
In this workshop, you will learn when it is important to use a mixed effects model to analyze your data.
We will walk you through the steps to conduct a linear mixed model analysis, check its assumptions, report results, and visually represent your model in R.
