Abstract

We propose an improved randomized response model for the simultaneous estimation of population means of two quantitative sensitive variables by using blank card option that make use of one scramble response and another fake response. The properties of the proposed estimator have been analyzed and empirical studies are performed to show its dominance over existing estimators along with enhance privacy protection of the respondents. Suitable recommendations have been made to the survey practitioners.

一种改进的随机响应模型，用于同时估计两个定量敏感变量的均值

摘要

我们提出了一种改进的随机响应模型，用于通过使用一个打乱响应和另一个假响应的空白卡选项同时估计两个定量敏感变量的总体均值。已经分析了提议的估计器的属性，并进行了实证研究，以显示其对现有估计器的优势，同时增强了受访者的隐私保护。已向调查从业人员提出了适当的建议。
