Summary: The problem of estimating the correlation coefficient using scrambled responses based on the B. H. Eichhorn and L. S. Hayre [J. Stat. Plan. Inference 7, 307–316 (1983)] model was considered by S. Singh, [“On improved strategies in survey sampling”, unpublished dissertation (1991)] who had studied the asymptotic behavior of the bias and variance expressions. As pointed out by A. Chaudhuri [Randomized response and indirect questioning techniques in surveys. Boca Raton, FL: CRC Press (2011; Zbl 1278.62001); D. R. Bellhouse, “Estimation of correlation in randomized response”, Surv. Methodol. 21, 13–19 (1995)] has considered the problem of estimating the correlation coefficient, but the details are cumbersome and are not reported in his monograph. Chaudhuri [loc. cit.] further indicates that efforts are needed to refine developments to estimate correlation coefficient to switch over to the utilization of procedures when only randomized response survey data are available. He mentioned that no literature of relevance seems available yet. In this chapter, an attempt has been made to answer the question raised by Chaudhuri [loc. cit].
