A Gentle Introduction to Random Slopes in Multilevel Modeling
…aka, how to look at cool interaction effects for nested data.
Do the words “random slopes model” or “random coefficients model” send shivers down your spine? These words don’t have to be so ominous. Journal editors are increasingly asking researchers to analyze their data using this particular approach, and for good reason.
In this Stat’s Amore training, Marc Diener will help you make sense of the concepts and data that you find in studies that use random slopes: multi-level models (MLM). You’ll learn the ideas behind random slope models, when to use this type of model, and how to go about adding variables into your model. A running example will be used to clarify the ideas and the meaning of the multilevel model results.
