Quatember, A. (2015). Pseudo-Populations - A Basic Concept in Statistical Surveys. Springer, Heidelberg.
For two reasons, artificial or pseudo-populations are a basic concept in statistical surveys: At first, this unified framework may substantially improve the users’ intuitive understanding of various aspects in the sampling theory. This is shown in the book for the probability and non-probability sampling schemes, different estimation strategies, small area estimation, the repair methods for occurred nonresponse, data imputation and weighting adjustment, as well as for randomized response questioning designs that are aimed to avoid nonresponse at all.
At second, in some cases pseudo-populations actually have to be generated physically: Examples are simulation studies in the field of survey sampling and a certain type of the finite population bootstrap.
