自适应两级序贯双重抽样

Adaptive two-stage sequential double sampling

Bardia Panahbehagh, Afshin Parvardeh, Babak Mohammadi

摘要:

在许多调查中,廉价的辅助变量可以帮助我们对主要变量做出更精确的估计。利用辅助变量的回归估计已被推广到罕见和集群人口。在传统的回归估计中,假设总体中辅助变量的均值是已知的。在许多调查中,我们没有关于辅助变量的如此广泛的信息。在本文中,我们提出了一个多阶段变量的两阶段序贯抽样的基础上,一个廉价的辅助变量与双重抽样形式的调查变量。辅助变量将用于设计和估计阶段。总体均值的估计采用两个不同系数的修正回归型估计。将使用Median和Thompson(2004)的一些模拟来研究结果。

英文摘要:

In many surveys inexpensive auxiliary variables are available that can help us to make more precise estimation about the main variable. Using auxiliary variable has been extended by regression estimators for rare and cluster populations. In conventional regression estimator it is assumed that the mean of auxiliary variable in the population is known. In many surveys we don't have such wide information about auxiliary variable. In this paper we present a multi-phase variant of two-stage sequential sampling based on an inexpensive auxiliary variable associated with the survey variable in the form of double sampling. The auxiliary variable will be used in both design and estimation stage. The population mean is estimated by a modified regression-type estimator with two different coefficient. Results will be investigated using some simulations following Median and Thompson (2004).
