使用普查数据模拟MPPS抽样方法的研究

MPPS抽样即多变量与规模成比例的概率抽样,是20世纪90年代才提出来的一种抽样设计。近年来,中国有关部门与美国农业部国家农业署合作,进行了MPPS抽样设计的试点,来解决多目标调查问题。但是MPPS抽样在中国的应用非常有限。对MPPS抽样进行简单的回顾,介绍了它的基本估计,并对其应用进行了数据模拟研究。模拟中采用了系统抽样和泊松抽样的方法,根据实际调查数据得到了明确的结果。还对泊松抽样的一种变形永久随机数抽样的方法进行了模拟研究,并对它的一种误用情况进行了模拟比较,得到了具有说服力的结果。

On Simulation About MPPS Sampling Method by Using the Census Data

MPPS sampling refers to the multivariate probability proportional to size sampling,which is proposed in 1990＇s.In recent years,the relevant survey agency in China conducted a pilot survey aiming on multi-purpose based on MPPS sample design which was collaborated with the National Agricultural Statistics Service（NASS） under the United States Department of Agriculture（USDA）.Until now the MPPS sampling method is not widely applied in China.This paper gives a brief review of MPPS sampling method including its basic estimation procedure,and demonstrates a simulation results by using the real agricultural census data.In our simulation,we compared the results from the systematic sampling and Poisson sampling,and illustrated the design effects by using the census data.In addition,we simulated the results from the Poisson sampling with the permanent random number,and through our simulation we would like to make a clearance to one of its misuse by demonstrating the persuasive results.
