Design-based estimators of totals, means or proportions in finite populations generally are functions of weighted sums. If each element selected into the sample is also observed, then for the calculation of the pi-estimator these weights are just the inverse inclusion probabilities of the...

The paper provides information on sample sizes and panel attrition in the German Socio-Economic Panel (GSOEP) for the years 1984-1999. Furthermore, results of the sequential estimation of non-response probabilities for the different subsamples of the GSOEP are described in detail.
