The proposed methods are compared to the Odumade and Singh and Singh and Grewal models through a simulation study. It is shown that the modified methods can be used more efficiently than those both models %K randomized response technique %K estimation of proportion %K relative efficiency %U https://journals.sagepub.com/doi/full/10.1177/0049124116661581
