Replication Methods of Variance Estimation Supported

• Stratified 2 PSUs/stratum
  • Balanced Repeated Replication (BRR)
  • Fay's BRR method (Fay)
  • Jackknife 2 (JK2)
• Stratified >2 PSUs/stratum
  • Jackknife n (JKn)

Creating Replicate Weights When Multiple Steps Are Used in Constructing Estimates

Weights are recomputed for each replicate subsample and reflect:

• Nonresponse adjustments
• Post-stratification
• Raking

Numbers of Replicates

• BRR, Fay - up to 512 with bundled orthogonal matrices, up to 9,984 with user supplied matrices
• Jackknife (JK1, JK2, JKn) - up to 9,999
