摘要:

本文详细讨论了无应答情况下简单随机抽样总体均值的估计问题。受Gupta和Shabbir(2008)的启发,我们提出了在无应答下使用辅助变量的总体均值估计类。在辅助变量的总体均值未知的情况下,利用双重抽样方案进行了理论研究。在理论结果的支持下,还进行了实证研究。

英文摘要:

The present paper presents the detail discussion on estimation of population mean in simple random sampling in the presence of non-response. Motivated by Gupta and Shabbir (2008), we have suggested the class of estimators of population mean using an auxiliary variable under non-response. A theoretical study is carried out using two-phase sampling scheme when the population mean of auxiliary variable is not known. An empirical study has also been done in the support of theoretical results.
