Improved Randomized Response Technique for Two Sensitive Attributes

Abstract

We proposed new and more ecient estimators for estimating population proportion of respondents belonging to two related sensitive attributes in survey sampling by extending the work of Mangat(1994). Our proposed estimators are more ecient than Lee et al (2013) simple and crossed model estimators as the population proportion of possessing the sensitive attribute increases.
