AN ALTERNATIVE ESTIMATOR FOR RANDOMIZED-RESPONSE SAMPLING WITH CONTINUOUS DISTRIBUTIONS FROM A DICHOTOMOUS POPULATION

In this paper, we introduce an alternative estimator of a population proportion from a dichotomous population when using randomized response sampling with continuous randomizing distributions. We also propose the alternative use of exponential randomizing densities, The estimator is obtained by method of moments and is compared with Franklin's (1989) estimator using normal and exponential distributions. The proposed estimator is more efficient than Franklin's (1989) estimator under suitable conditions for the two distributions.
