Assessment of Scrambled Response on Second Call in Two-Occasion Successive Sampling under Non-Response

摘要

This paper is an attempt to analyze the effect of modified Hansen and Hurwitz (1946) technique to estimate the current population mean in case of quantitative sensitive variable in two-occasion successive sampling. The problem of evaluating the degreeof privacy protection is also considered. Randomized linear model and their special cases have been considered on current occasion and properties of the proposed estimation strategy have been examined. Simulation studies are carried out to evaluate theperformances of the proposed estimator with respect to estimators under (i) complete response and(ii) under Hansen and Hurwitz (1946) technique. Analytical and numerical comparisons of some well-known scrambled models have been carried out in terms of efficiency and privacy protection. Results have proved the effectiveness of the suggested estimation strategy in real life situations.
