An optional randomized response sampling technique using non-stigmatized attribute

N. S. Mangat
In this study, an optional randomized response strategy has been proposed using non-stigmatized attribute. The proportion of the non-sensitive attribute has been assumed to be known. Though the proposed estimator is biased, the bias can be reduced by choosing the parameters suitably. The situations, where the suggested technique fares well as compared to original unrelated question randomized response procedure have been identified.
