Webb7 okt. 2015 · For this guidance, we will denote available methods in SAS Version 9.3. Note that although GENMOD is the standard SAS procedure for implementing GEE models, the methods that are currently available from SAS with small-sample variance correction for marginal models are only implemented in the procedure GLIMMIX and were not …
