This paper shows how PROC LOGISTIC, ODS Output and SAS MACROS can be used to proactively identify structures in the input data that may affect the stability of logistic regression models and allow for well-informed preemptive adjustments when necessary. Thus we are introducing a standardized ...
If the data were independent, we could deal with this by using PROC LOGISTIC or PROC GENMOD. For mixed models, SAS supplies two procedures: PROC NLMIXED and PROC GLIMMIX, details of which are presented below. Here we discuss some complications that dichotomous variables present for multilevel ...

Similarly, participants interviewed in December or January are significantly more likely to report adequate or long nightly sleep when the sleep variable was dichotomized in PROC 5 SURVEYLOGISTIC, adjusting for the same covariates as the linear model (p=0.002, Table 3). While these results are ...
