摘要
研究数量特征敏感性问题的调查方法,设计了一种数量特征敏感性问题的随机化回答改进模型,计算了改进模型的估计量及其方差,并对改进模型进行了分析,得出改进模型具有较好的精度.
This paper studies the survey sampling of quantity sensitive question, one improvement randomized response model of quantity sensitive question is designed. In the new model, the unbiased estimator of population mean and its variance are given, further, we demonstrate that new model has better properties compared with those of the previous on.
