摘要
抽样调查下有限总体的估计,一般是基于传统抽样设计,另一种是基于超总体模型,即假定总体取值不是确定的,而是由超总体模型产生的。本文以简单随机抽样和抽样为例,揭示了在不同情况下,如何得到超总体模型下有限总体的估计,并对基于设计和基于模型两种观点进行了比较分析。
The estimation for finite population in sample survey is usually based on traditional sample design. Another type is based on superpopulation models, in which the actual values for the finite population is supposed to be generated from superpopulation model. This paper discusses how to assume the superpopulation model and estimate the population, taking SRS and PPS for examples. And the comparative analysis is done between the design-based and the model-based methods.
