AbstractInverse sampling is an adap

Abstract
Inverse sampling is an adaptive method whereby it is the sample size that is adaptive. On the basis of a new proof, Murthy’s estimator can now be applied with or without adaptive cluster sampling to inverse sampling to provide unbiased estimators of the mean and variance of the mean estimator. A number of sequential plans along with parameter estimates are considered including a general inverse sampling design, multiple inverse sampling when subpopulation sizes are known, quota sampling, multiple inverse sampling, and truncated multiple inverse sampling.

摘要逆抽样是一种自适应方法，即它是自适应的样本量。在一个新的证据的基础上，Murthy的估计现在可以应用或不适应性整群抽样逆抽样提供的平均估计的均值和方差的无偏估计量。被认为是一个数量的顺序的计划，包括参数估计，包括一般的逆抽样设计，多个逆抽样时，亚群的大小是已知的，配额抽样，多个逆采样，和截断的多个逆采样。
