Abstract
The current study deals with imputation of item non-response in probability proportional to size (PPS) sampling. A new imputation procedure is proposed by using the known co-variance between the study variable and the auxiliary variable in the case of quantitative sensitive study variable by considering the non-response in a randomization mechanism on the second call. An empirical study is conducted at the optimum values ofkogandnogfor the relative comparisons of ratio, difference, and proposed estimators, respectively, with the Hansen-Hurwitz estimator.
