调查从业人员对如何最好地利用伙伴关系改进数据收集过程越来越感兴趣。一个特别的问题是,是否有可能在实地工作中及早查明那些可能需要很长时间,因而需要大量财政和人力资源,直到面谈结束的样本案件。更具体地说,我们的目标是确定长期不成功的调用序列的情况下。本文对通话记录数据进行建模,预测最终通话结果和通话序列的长度。单独的二进制和联合多项逻辑模型的两个结果,占家庭内的采访者的集群。特别感兴趣的是,以确定解释变量预测的最终结果和长度的调用序列。这项研究使用了英国大规模纵向调查“理解社会”的数据。这项工作具有响应性和适应性的调查设计的影响。结果表明,建模结果和呼叫序列的长度共同提高了模型的拟合。先前呼叫的结果,特别是来自最近呼叫的结果,具有高度的预测性。电话的时间和面试官的观察变量,虽然在模型中显着,只有轻微的提高预测能力。
Survey practitioners are increasingly interested in how best to use paradata to improve data collection processes. One particular question is whether it is possible to identify early during fieldwork those sample cases that may require a long time, and therefore a lot of financial and staff resources, until interviewing is completed. More specifically, we aim to identify cases with long unsuccessful call sequences. This paper models call record data predicting final call outcome and length of a call sequence. Separate binary and joint multinomial logistic models for the two outcomes are presented, accounting for the clustering of households within interviewers. Of particular interest is to identify explanatory variables that predict final outcome and length of a call sequence. The study uses data from Understanding Society, a large-scale UK longitudinal survey. The work has implications for responsive and adaptive survey designs. The results indicate that modeling outcome and length of a call sequence jointly improves the fit of the model. Outcomes of previous calls, in particular from the most recent call, are highly predictive. The timing of calls and interviewer observation variables, although significant in the models, only slightly improve the predictive power.
