Abstract:

There have been many alternativerandomized response strategies for implementing survey on sensitive question so far. And most of these
strategies have improved survey efficiency by choosing approprite design parameters. However, two different procedures with common design parameter values are of diferent  protection degree to the respondents. Some earlier comparisons of those strategies are unfair  because those
comparisons do not provide the same degree of protection to the respondents in the two models. In this paper, theauthors compare exactly the
efficiency of some earlier strategies under same protection degree to respondents.  The obtained results show that these earlier randomized response strategies must be  reevaluated.
