چکیده
Abstract: In this paper we have suggested a general procedure for estimating the population mean through defining a class of estimators. Many of the existing estimators are shown particular members of the proposed class of estimators. It has been shown to the first degree of approximation that mean squared error (MSE) of the proposed class of estimators are better than the competing ratio, regression, exponential ratiotype and other ratio-type estimators considered here. Numerical illustrations are given in support of the present study.

The present investigation considers the problem of estimating the mean of a sensitive quantitative variable μA in a human population survey, using the scrambled response technique suggested by Ryu, Kim, Heo and Park (On stratified randomized response sampling, Model Assisted Statistics and Application 1(1), 31–36, 2005–2006). Specifically, using the prior estimate (or guessed mean) of the mean ...
