Abstract
In this article, a new estimator for estimating the proportion of sensitive attribute is constructed based on Warner [1] and Singh and Joarder [2] estimators. The results are derived in case respondents are selected by simple random sampling with replacement (SRSWR) and without replacement (SRSWOR). The proposed estimator is unbiased in both the cases and is more efficient than the estimator proposed by Singh and Joarder [2].
