Use of directly calculated RSEs
RSEs for 2010 Workforce Participation and Workplace Flexibility Survey estimates are published in 'direct' form. Estimates have been calculated for each separate estimate and published individually. The Jackknife method of variance estimation is used for this process, which involves the calculation of 30 'replicate' estimates based on 30 different sub-samples of the original sample. The variability of estimates obtained from these sub samples is used to estimate the sample variability surrounding the main estimate. Previously a statistical model was produced that relates the size of estimates to their corresponding RSEs, and this information was displayed via a 'standard errors of estimates' table.
