Optional unrelated-question randomized response models

Sat Gupta, Anna Tuck, Tracy Spears Gill and Mary Crowe

Vol. 6 (2013), No. 4, 483–492

We propose a generalization of Greenberg’s unrelated-question randomized response model allowing subjects the option of giving a correct response if they find the survey question nonsensitive, and to give a scrambled response if they find the question sensitive. Models are provided for both the binary response and the quantitative response situations. Mathematical properties of the proposed models are examined and validated with computer simulations.
