Abstract:
|
In spite of having a broad range of applications in surveys with sensitive questions, randomized response (RR) approach is limited in several ways including (i) a lack of reproducibility; (ii) a lack of trust from interviewees; and (iii) higher cost due to the use of randomizing devices. This article compares the efficiency between the non-randomized response (NRR) triangular model and the randomized Warner model. In addition, we propose the concept of the degree of privacy protection between the triangular model and the Warner model to reflect the extent the privacy is protected. Our studies show that not only the NRR approach is free of the limitations of the RR approach but also it in fact increase the (v) relative efficiency and (vi) the degree of privacy protection. Thus, the NRR approach offers an attractive alternative to the RR approach.
