ABSTRACT
Ahmed, Sedory and Singh (2016) have introduced a pioneer idea problem of simultaneous estimation of means of two quantitative sensitive variables by using only one randomized response and another pseudo response from a respondent in a sample. They considered the use of simple random and stratified random sampling. In this paper, we have considered the problem of estimation of population totals of two sensitive variables by making use of complex survey designs. The bias and variance expression of the resultant estimators are derived. The performance of the new estimators has been investigated through an extensive simulation study using R programming.
Keywords: Two sensitive variables, estimation of totals, variance, protection of respondents.
