WebbFor binary response models, PROC GLIMMIX can estimate fixed effects, random effects, and correlated errors models. PROC GLIMMIX also supports the estimation of fixed- and random-effect multinomial response models. However, the procedure does not support the estimation of correlated errors (R-side random effects) for multinomial response models. ctr threshold limit
