裂区设计连续调查的条件影响及重抽样核实调整
The Effect and Double Adjustment of Condition Effect in Split Panel Surveys
-
摘要: 条件的影响是有匹配样本的连续调查特有的计量误差来源.本文在变异计量误差模型之下,研究了未调整时条件影响对两期裂区设计连续调查中采用的组合差估计量的统计影响,同时提出了重抽样核实调整方法,得到了调整后的无偏估计量,计算了调整后估计量的方差.讨论了调整后估计量准确度比未调整估计量准确度高的条件.Abstract: Condition Effect is an important source of non-sampling error in continuous surveys with matched samples. In this paper, we studied the statistical effect of the condition effect for the combined difference estimator in split panel surveys, proposed an adjusted estimator under a double sampling verification scheme, calculated the variance of the adjusted estimator, discuss the conditions under which the adjusted estimator has higher accurity.
