Zawar Hussain, Salman Arif Cheema, Sidra Zafar

In this study, a Bayesian estimation of population proportion of a stigmatized attribute has been considered and a Bayes estimator is developed when the information from the survey respondents is collected using the randomized response technique (RRT) by Mangat and Singh (1990).
