strategy of model building in PROC LOGISTIC (see also our SUGI'26 and SUGI'28 papers) could work for PROC PHREG as well. Our suggestion was based on the close similarity between logistic and Cox's regressions, including information criteria and stepwise, forward, backward and score options. He...

In these cases, PROC SURVEYLOGISTIC is appropriate because it takes this design into account (An, 2002). Both PROC SURVEYREG and PROC SURVEYLOGISTIC use Taylor series or resampling methods to estimate sampling errors of the estimators based on the complex survey design, depending on the options ...

Richardson, Van Andel Research Institute, Grand Rapids, MI ABSTRACT PROC LOGISTIC has many useful features for model selection and the understanding of fitted models. The standard generated output will give valuable insight into important information such as significant variables and odds ratio confidence...
