PROC LOGISTIC gives ML tting of binary response models, cumulative link models for ordinal responses, and baseline-category logit models for nominal responses. (PROC SURVEYLOGISTIC ts binary and multi-category regression models to sur-vey data by incorporating the sample design into the analysis and using the method of pseudo ML.)
