Design Summary

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
