  2. SUDAAN DESIGN COMMANDS With Without Replication Replacement Replacement Method WR WOR Jackknife UNEQWOR BRR (Fay) STRWR STRWOR SRS Adapted from Page 3-3 SUDAAN Manual, Vol. 1

  3. DESIGN OPTION FLOWCHART FOR LINEARIZATION METHOD PSU SELECTION WITH REPLACEMENT (n / N small, ALL strata) WITHOUT REPLACEMENT (n / N large, ANY stratum) NOT CLUSTERED equal prob. W/in strata CLUSTERED CLUSTERED NOT CLUSTERED STRWOR STRWR WR WOR equal prob. ALL stages UNEQWOR UNequal prob. ONLY FIRST stage Adapted from Page 3-7 SUDAAN Manual, Vol. 1
