Back to Basics with Mixed-Effects Models: Nine Take-Away Points

Multilevel mixed effects models are widely used in organizational behavior and organizational psychology to test and advance theory. At times, however, the complexity of the models leads researchers to draw erroneous inferences or otherwise use the models in less than optimal ways. We present nine take-away points intended to enhance the theoretical precision and utility of the models. We demonstrate our points using two types of simulated data:...
