Variance estimation for measures of change in probability sampling , Southampton, GB University of Southampton 21pp.
(S3RI Methodology Working Papers, M03/10).
We propose to estimate the design variance of absolute changes between two cross-sectional estimators under rotating sampling schemes. We show that the variance estimator proposed is generally positive. We also propose possible extensions for stratified samples, with dynamic stratification; that is, when units move between strata and new strata are created at the second waves.
