Hemant K. Verma, R. D. Singh, Rajesh Singh

摘要:

本文研究了在无响应情况下利用辅助变量信息估计系统抽样总体均值的问题。本文提出了系统抽样中几种修正的比型、乘积型和差型估计,并研究了它们的性质。推导了一阶近似下的均方误差表达式。进行了实证研究,以判断最好的估计建议的估计。

英文摘要:

In this paper we have considered the problem of estimating the population mean in systematic sampling using information on an auxiliary variable in presence of non response. Some modified ratio, product and difference type estimators in systematic sampling have been suggested and their properties are studied. The expressions of mean squared errors (MSEs) up to the first order of approximation are derived. An empirical study is carried out to judge the best estimator out of the suggested estimators.
