Lesson 18: Mixed Effects Models

Overview Section

In this chapter we'll make a quick non-technical overview of fitting mixed effects models, focusing on the use of the function lme().


Upon completion of this lesson, you should be able to:

  • Recognize when a mixed effects model might be appropriate
  • Be able to fit simple repeated measures models with lme()
  • Be able to fit simple split-plot models with lme()
