This post is going to follow along and expand on a well-known tutorial for Mixed Effect Linear Models by Bodo Winters, a lecturer in Cognitive Linguistics at the University of Birmingham, Dept. of English Language and Applied Linguistics. While this tutorial will generally follow Winter’s, I have added additional detail for EDA, expanded the details re: code & errors that are encountered, and added notes from many other sources on Mixed Effect Models (see the Sources section at the end for links) - let’s get started!
