二阶抽样中二级单位总样本量的分配

ALLOCATION OF THE SECOND-STAGE SAMPLING UNITS IN TWO STAGE SAMPLING

  • 摘要: 本文讨论了二阶抽样中一阶抽样为不等概率抽样、二阶抽样为简单随机抽样时,二级单位总样本量的几种分配方案。给出各种分配方案下总体总值的Horvitz-Thompson估计量的方差。并加以比较,最后给出最优分配方案。

     

    Abstract: Recently, Schneeberger. H considered allocations of the second-stage sampling units in two stage sampling according to simple random method at both stages. In this paper, we consider allocations of the second-stage sampling units in two-stage sampling according to unequal probability method at first stage and simple random method at second stage. We compare the variations of the estimators for the population total with various allocations of the second-stage sampling units, indicating optimum allocation of the second-stage sampling units and respective gains in precision.
