固定样组纵向调查“间歇式”期单元无回答的加权调整

Weighting Adjustment of Wave Non-response in Panel Surveys

期单元无回答误差是固定样组纵向调查中经常出现的一类非抽样误差.如果不对之进行调整,则往往造成估计量的偏差.已经提出的两种加权调整方法不易处理“间歇式”期单元无回答.在本文中,我们提出了纵横加权调整方法,这一方法克服了已有方法的不足.我们所作的模拟研究表明,纵横加权方法降低了估计量的偏差,并在作两调查期指标均值变化分析时,充分利用了两期回答状态的相关信息,提高了变化估计量的准确度.

Wave non-response is a sort of non-sampling error that often occurs in panel surveys. It usually causes bias of the estimator without adjustment. The two existing weighting adjustments encounter complexities in dealing with non-monotone wave non-responses. In this paper, we propose a novel weighting method, column and row weighting method, to adjust for the non-monotone wave non-response in panel surveys. Our method avoids the complexity of the existing methods. The simulation study We did shows that our method reduce the bias of the estimators and increase the accuracy of the estimator of the net change between two waves.
