October 2016 Member Webinar: Generalized Linear Mixed Models

by Karen Grace-Martin


A Gentle Introduction to Generalized Linear Mixed Models

Generalized linear mixed models (GLMMs) are incredibly useful—but they’re also a hard nut to crack.

As an extension of generalized linear models, GLMMs include both fixed and random effects. They are particularly useful when an outcome variable and a set of predictor variables are measured repeatedly over time and the outcome variable is a binary, nominal, ordinal or count variable. These models accommodate nesting of subjects in higher level units such as schools, hospitals, etc., and can also incorporate predictor variables collected at these higher levels.

In this webinar, we’ll provide a gentle introduction to GLMMs, discussing issues like:

  • What GLMMs are and when to use them
  • What to consider when specifying GLMMs
  • How to compare competing GLMMs to identify the most adequate model for the data
  • How to interpret model fit information
  • What types of inference and prediction are supported by GLMMs
  • How to check the validity of model assumptions

You’ll become familiar with the major issues involved in working with GLMMs so you can more easily transition to using these models in your work.
