不等概率抽取群单位时样本量的间接计算

讨论了应用设计效应间接计算不等概率抽群的单级整群抽样和二阶段抽样方案样本量的问题,其中包括：所论抽样方案设计效应的估计;估计所论总体的方差,并根据精度要求计算简单随机抽取基本抽样单元时所需的样本量;用设计效应将上述样本量换算成所论抽样方案需要的样本量。

The Indirect Calculation Of Sample Size By Using Unequal-probability Sampling To The Selected Group Unit

This paper discusses the questions of how to apply the designing efficient on indirect calculation of sample size in the single-stage cluster sampling and two-stage sampling of unequal-probability sampling.These include: the estimation of the designing efficient mentioned;the variance of population estimated;the sample size in accordance with the requirements of precision when sampling the sample group by simple random sampling;the sample size by converting the designing efficient into the above-mentioned s...
