Two mixed randomized response models under simple and stratied random sampling with replacement schemes

We have proposed two mixed randomized response models for surveying sensitive issues. The properties of proposed estimators are derived under the simple and stratified random sampling schemes while considering completely and less than completely truthful reporting cases. We proved that the proposed models are unconditionally efficient than [13, 15, 16, 20]. In order to get the idea of gain in efficiency and model stability numerical and graphical efficiency comparisons are done for the two models under two mentioned cases.
