WebbThis approach assumes that the correlation arises among repeated measures as the regression coeﬃcients vary across individuals. That is, each subject is assumed to have an (unobserved) underlying level of response which persists across thepmeasurements. This subject eﬀect is treated as random and the model becomes WebbPROC GENMOD in SAS can implement the GEE method presented in Chapter 9, using the REPEATED statement to specify the variable name that identifies the subjects for each cluster.
