WebbThe GENMOD procedure in SAS® allows the extension of traditional linear model theory to generalized linear models by allowing the mean of a population to depend on a linear predictor through a nonlinear link function. In this paper we investigate a binary outcome modeling approach using PROC LOGISTIC and PROC GENMOD with the link function. WebbFitting the GEE Model. The model for the clustered responses as a function of only the question type would look like this. log ( π i j 1 − π i j) = β 0 + M e d i j β 1 + S c i i j β 2. where π i j is the probability that the i t h subject answers "A great deal" to the j t h question.
