Jan A. van den Brakel Design and analysis of experiments embedded in complex sample surveys
Previous research has proposed a design-based analysis procedure for experiments that are embedded in complex sampling designs in which the ultimate sampling units of an on-going 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 whether sample means that are observed under various survey implementations are significantly different. This approach is generalized to experimental...

Jan A. van den Brakel | J.G. Bethlehem Model-based estimation for official statistics
This paper summarizes the advantages and disadvantages of design-based and model-assisted estimation procedures that are widely applied by most of the European national statistical institutes. Several situations are identified were model-based approaches can have additional value in the production of official statistics, e.g. to deal with small sample sizes, measurement errors and discontinuities due to survey redesigns. It is concluded that there is a case for having official releases and time series,...

Jan A. van den Brakel Design and analysis of experiment embedded in complex surveys
This research project focuses upon the development of statistical methods for the design and analysis of field experiments embedded in ongoing surveys in order to support research aiming at the improvement of the survey process. Embedded experiments are particularly appropriate if interest is focussed on the quantification of the effect of alternative survey methodologies on estimates of finite population parameters of the survey. In these experiments the sample of an ongoing survey is randomly divided...

Jan A. van den Brakel | R.H. Renssen Design and analysis of experiments embedded in sample surveys
This paper focusses upon design and analysis of large scaled field experiments embedded in ongoing surveys. Historically, experimental designs and sampling theory form two separated domains in the field of applied statistics. However, by the design and analysis of embedded experiments, statistical methods from the fields of experimental designs and sampling theory can be combined in order to improve the quality and efficiency of these experiments. It is discussed how parallels between randomized...

Jan A. van den Brakel | Paul Smith | Simon Compton Quality procedures for survey transitions experiments and discontinuities
To maintain uninterrupted time series, surveys conducted by national statistical institutes are often kept unchanged as long as possible. When a change is proposed to improve the methods, it may affect the continuity of these series. It is important to minimise the impact so as to minimise the inconvenience for users. In this paper we set out the steps in an orderly transition, provide practical guidance on how to minimise discontinuities, and review methods for dealing with discontinuities if they...

Jan A. van den Brakel Design-based analysis of embedded experiments with applications in the Dutch labour force survey
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...
