A new efficient unrelated randomized response model

A new improved randomized response model with application to compulsory motor insurance

“…The main approach, adopted by most research, for increasing the efficiency of RRT is based on design modification. Different modifications of Warner's [ 1 ] RR were developed by various authors, just to name a few, Greenberg et al [ 25 ]; Moors [ 26 ]; Raghavarao [ 27 ]; Mangat and Singh [ 28 ]; Kuk [ 29 ]; Mangat [ 30 ]; Singh et al [ 31 ]; Bhargava and Singh [ 32 ]; Singh et al [ 33 ]; Haung [ 34 ]; Chang et al [ 35 ]; Gupta et al [ 36 ]; Gjestvang and Singh [ 37 ]; Perri [ 38 ]; Abdelfatah and Mazloum [ 39 ]; Batool et al [ 40 ]; Singh and Gorey [ 41 ]; Tarray and Singh [ 42 ]; Narjis and Shabbir [ 43 ]; Singh and Suman [ 44 ].…”

An Improved Two-stage Randomized Response Model for Estimating the Proportion of Sensitive Attribute

“…N. Singh and Suman (2019); Abdelfatah and Mazloum (2015, 2016); Batool, Shabbir, and Hussain (2017); H. P. Singh and Tarray (2016); H. P. Singh and Gorey (2017); Tarray and Singh (2018); Narjis and Shabbir (2018, 2019); and Hussain, Cheema, and Hussain (2020).…”

“…In optional RRT model, respondents are requested to provide the truthful response if he or she considers the question to be nonsensitive and use the randomization device if he or she considers the question sensitive and provide the response after using randomization device. Some developments to estimate the proportion of sensitive attribute are due to Greenberg et al (1969); Chaudhuri and Mukerjee (1988); Mangat and Singh (1990); Mahmood, Singh, and Horn (1998); Perri (2008); G. N. Singh and Suman (2019); Mazloum (2015, 2016); Batool, Shabbir, and Hussain (2017); H. P. Singh and Tarray (2016); H. P. Singh and Gorey (2017); Tarray and Singh (2018); Shabbir (2018, 2019); and Hussain, Cheema, and Hussain (2020).…”
