CALCULATION OF DESIGN EFFETS

It is common practice to estimate the design effect due to weighting by 1 plus the variance of the weights (see Bruce D. Spencer, "An approximate design effect for unequal weighting when measurements may correlate with selection probabilities", Survey Methodology, December 2000). This calculator can estimate various scenarios of design effects for a stratified sample of a population.
