系统抽样中一种改进的估计

An Improved Estimator In Systematic Sampling

Rajesh Singh, Sachin Malik, Viplav K. Singh

摘要:

本文采用Bahl和Tuteja(1991)的估计量进行辅助信息系统抽样。在系统抽样下,利用Bedi(1996)变换给出了一种改进的估计量.导出了一阶近似下的偏差和均方误差的表达式。它已被证明,所提出的估计性能优于许多现有的估计。最后给出了一个数值例子来支持理论结果。

英文摘要:

In this paper we have adapted Bahl and Tuteja (1991) estimator in systematic sampling using auxiliary information. Using Bedi (1996) transformation an improved estimator is also proposed under systematic sampling. The expressions of bias and mean square error up to the first order of approximation are derived. It has been shown that the proposed estimator performs better than many existing estimators. A numerical example is included to support the theoretical results.
