When fitting a model in these procedures, odds ratios are only possible when the response is binary or multinomial (DISTBIN or DISTMULT) and the link involves a logit function (LINKLOGIT or LINKCUMLOGIT). These correlation matrices are used in a GEE algorithm (sketched below) in PROC GENMOD. 4479), and 5.
