Statistical Analysis with the GLIMMIX Procedure

This course focuses on the GLIMMIX procedure, a procedure for fitting generalized linear mixed models.

• analyze binomial data with random effects
• fit a Poisson regression model and a beta regression model with and without random effects
• analyze repeated measures data with discrete outcomes
• perform post-processing analysis
• use the EFFECT statement to define customized model effects
• jointly model multivariate responses with different distributions
• deal with convergence issues.
