Abstract:	The well-known design effect decomposition model proposed by Kish (1987) is often used to evaluate the efficiency of two features, clustering and unequal weighting. For complex sample designs involving other features such as stratification and PPS sampling of clusters, the model lumps all the features other than unequal weighting under the design effect component due to clustering. To provide separate evaluations of features, we propose a decomposition model extending Park et al. (2003). We also compare the Kish and proposed models and their respective design effect component models through simulation.
