摘要: 本文在使用以正态分布作为随机化分布的随机化回答调查法的情况下;给出了二分总体中对一敏感性问题属于A类所占比例的θ的一种新的估计量,并利用Frankin(1989)1及Chua和Chiang(1995)2给出的估计量构造了一种协方差改进估计,然后对这几种估计量进行了比较,最后给出了苦干定理的证明。Abstract: In this paper, we introduce an alternative estimator of a population proportions from a dichotomous population when using randomized response sampling with a normal randomizing distribution. We also propose a covariance adjustment estimator baized on Frankin’s(1989) estimator and Chua’s(1995) estimator. Finally, we compared these estimators.
