Abstract
In this article, two non-randomized scrambling models have been presented for estimation of mean of a quantitative sensitive attribute. Information on two unrelated non-sensitive qualitative attributes have been utilized for the purpose. An extensive simulation study has been conducted to compare the performance of the proposed models with respect to a contemporary model in terms of both percentage relative efficiency and privacy protection for various values of the parameters. The encouraging results suggest that the proposed models may be useful for survey statisticians in their field work.
