Two Randomized Response Techniques For Investigating The Quantitative Characteristic Of Sensitive Question

Two Randomized Response Techniques For Investigating The Quantitative Characteristic Of Sensitive QuestionThe Randomized Response Technique(RRT),which was originally developed for qualitative purposes, is being developed for quatitative purposes which is more complex. In practice,we may often have to deal with quantitative sensitive characters or variables. In the 1970's,Greenberg et oLproposed some randomized response techniques for investigating the quantitative characteristic of sensitive question.In this article,we discuss two main methods -the unrelated-question model and the random amputation model.Because the latter is more simple and convenient but can't protect the privacy of the interviewees very well, we suggest two modified methods baesd on it and make comparisons of them.
