An assessment of balanced sampling for use in business surveys (joint work with Li-Chun Zhang) Seminar

Abstract: In recent years the cube method (Deville & Tillé (2004) Biometrika 91 893-912) has made the selection of approximately balanced samples more practical. Exact balanced sampling solutions do not, however exist in all cases, and then the algorithm must choose between satisfying the given selection probabilities and satisfying the balancing equations. Current implementations of the cube method prefer the selection probabilities. We present an alternative approach to the selection of samples which minimises the deviation from balance, and test its application through some simulation studies.
