Some Methods of Inclusion Probability Proportional to Size Sampling
若干入样概率与规模成比例的抽样方法
SUMMARY This article proposes a sampling scheme which involves creating a sampling design to ensure inclusion probability proportional to size selection. The sampling design is created through constructing a sample space in which the population units occur in proportion to their sizes and every pair of units occurs in such a way as to provide a non-negative and stable variance estimator. The selection procedure is then extremely simple and the values of the inclusion…
