SURVEYFREQ Procedure

The SURVEYFREQ procedure now provides variance estimation by balanced repeated replication (BRR) and the jackknife methods, in addition to the Taylor series method. You can provide replicate weights for the new replication methods with a REPWEIGHTS statement, or the procedure can construct the replicate weights. PROC SURVEYFREQ now computes odds ratio and relative risk estimates. The new NOMCAR option in the PROC SURVEYFREQ statement requests a subpopulation analysis of the set of respondents for Taylor series variance estimation.
