When you specify a CLUSTER statement or a STRATA statement, the procedure displays a "Design Summary" table, which provides the following sample design information:
Number of Strata, if you specify a STRATA statement
Number of Strata Collapsed, if the procedure collapses strata
Number of Clusters, if you specify a CLUSTER statement
Overall Sampling Rate used to calculate the design effect, if you specify the DEFF option in the MODEL statement
