| Abstract: | In the present study, we develop theory for Takahasi and Sakasegawa's (1977) suggest ion and propose a new randomized response model suitable for mail surveys. The proposed model based estimator is unbiased and is always more efficient than the estimator based on Takahasi and Sakasegawa model. |
