Jan A. van den Brakel Design-based analysis of embedded experiments with applications in the Dutch labour force survey
Gedrukt boek
In a series of papers a design-based analysis procedure is proposed for experiments embedded in complex sampling designs in which the ultimate sampling units of an ongoing sample survey are randomized over different treatments according to completely randomized designs or randomized block designs. Design-based Wald and t-statistics are applied to test hypotheses about differences between sample means observed under different survey implementations, Van den Brakel and Renssen (1998, 2005) and Van den Brakel and Van Berkel (2002). In this paper, this approach is generalized to experimental designs in which clusters of sampling units are randomized over the different treatments. Furthermore, test statistics are derived to test hypotheses about ratios of two sample estimates. The methods are illustrated with a simulation study and real life applications of experiments embedded in the Dutch Labour Force Survey. The functionality of a software package developed to conduct these analyses is described
