Usage Note 24476: How can I get predicted values from my model fit with PROC SURVEYLOGISTIC?
Beginning in SAS 9.2, you can use the OUTPUT statement to get the predicted probabilities and confidence intervals.
Prior to SAS 9.2, PROC SURVEYLOGISTIC does not have an option to produce predicted values. Because the parameters on which the predicted values are based are invariant to the design effect, you can run the equivalent model in PROC LOGISTIC and obtain correct predicted values using the OUTPUT statement. However, because the standard errors are affected by the study design, any function of the covariance matrix of the parameters (such as confidence intervals) provided by PROC LOGISTIC are not correct.

For software releases that are not yet generally available, the Fixed
Release is the software release in which the problem is planned to be
fixed.
