SURVEYMEANS Procedure

The SURVEYMEANS 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. The new NOMCAR option in the PROC SURVEYMEANS statement requests a subpopulation analysis of the set of respondents for Taylor series variance estimation. PROC SURVEYMEANS now computes percentiles (Woodruff variance estimation only).
