Efficienza e protezione della privacy nei Randomized Response Model.

Randomized response is a method used in statistical surveys whose goal is to reduce or eliminate respons errors wich occour when respondents are queired aboput sensitive or highly personal matters. In this work the goals are to analyze and compare the respondent provacy protection in some randomized response models according to efficiency and privacy protection. We prove thta some single and double randomization models give no advantage in terms of efficiency under the condition of equal respondent protection compared to Warner's and simmons' models.
