Use of scrambled responses on two occasions successive sampling under non-response

Abstract

In this paper, we deal with a problem of non-response on two successive occasions when the study character becomes sensitive in nature on second occasion. Estimators are formulated by considering two cases of non-response, (i) when non-response on both occasions, (ii) when non-response on current occasion only. Expressions for mean squared errors (MSEs) are derived under large sample approximation and the optimum replacement strategies are also discussed. A numerical study is carried out in support of the proposed technique.
