An Efficient Mixed Randomized Response Model for Sensitive Characteristic in Sample Survey
Keywords:randomized response technique, dichotomous, estimation of proportion, privacy, innocuous variable, sensitive characteristic
This paper proposes an efficient mixed randomized response (RR) model for estimating the proportion of individuals who possess to the sensitive attribute in the given population under both the conditions completely truthful reporting as well as less than completely truthful reporting and examined its properties. The proposed models are found to be dominant over Kim and Warde  model. It has also been extended for stratified random sampling. Numerical illustrations are presented to support the theoretical results.
