The GLIMMIX procedure was first released as a Web download add-on procedure to SAS/STATÃ’ in SAS 9.1 in the 32-bit Windows operating environment. It was subsequently released as a Web download for SAS 9.1.3 in UNIX and Linux environments. This paper describes the key changes and enhancements to PROC GLIMMIX between the SAS 9.1 and SAS 9.2 releases. Enhancements fall into several categories: statistical estimation, model building, post-processing, and miscellaneous other features. For example, new estimation methods and covariance structures enable parameter estimation with reduced bias in more flexible generalized linear mixed models. A new statement provides a comprehensive facility to test hypotheses about covariance parameters.
