Reliability of estimates
Each record on the household level and person level contains 60 replicate weights in addition to the main weight. By using these replicate weights, it is possible to calculate standard errors for weighted estimates produced from the microdata.
This method is known as Group Jackknife variance estimation. For more information on the Group Jackknife method of standard error estimation, see Research Paper: Weighting and Standard Error Estimation for ABS Household Surveys (Methodology Advisory Committee), July 1999 (cat. no. 1352.0.55.029).
Use of the 60 group Jackknife method for complex estimates, such as regression parameters from a statistical model, is not straightforward and may not be appropriate. The method as described does not apply to investigations where survey weights are not used, such as in unweighted statistical modelling.
