多阶段抽样比率估计及其样本量的选择
Ratio estimation method and optimum allocation of sample sizes in multi-stage sampling
摘要
Abstract
We give the approximation formulas of the variance of the sample ratio estimator for a population mean and its asymptotically non-biased estimator in multi-stage sampling. We also give the formulas of optimum allocation of the sample sizes of the sample ratio estimator in multi - stage sampling with the proportional allocations of sample sizes in the second to ( n )-th sampling under the cost function.关键词
