Edgeworth expansions for two‐stage sampling with applications to stratified and cluster sampling [PDF]

open access: yesCanadian Journal of Statistics, 2015
AbstractA two‐term Edgeworth expansion for the standardized version of the sample total in a two‐stage sampling design is derived. In particular, for the commonly used stratified and cluster sampling schemes, formal two‐term asymptotic expansions are obtained for theStudentizedversions of the sample total.

A Study of Sample Size for Two-Stage Cluster Sampling [PDF]

open access: yesUngyong T'onggye Yon'gu = the Korean Journal of Applied Statistics, 2011
In a large scale survey, cluster sampling design in which a set of observation units called clusters are selected is often used to satisfy practical restrictions on time and cost. Especially, a two stage cluster sampling design is preferred when a strong intra-class correlation exists among observation units.
