Estimation of Exponential Ratio-cum-Exponential dual to Ratio Imputation Techniques in Sample Survey

Jyotishman Das, B. K. Singh


In most of the large-scale surveys, the problems of non-response occur. To deal with nonresponse, several techniques are available in use, one of the best among them is imputation method. In this paper, some exponential ratio-cum-exponential dual to ratio imputation techniques and their corresponding estimators are proposed for evaluating the population mean of the study variable. Also the bias, the mean square error and the percentage relative efficiency are evaluated to examine the adaptability of the proposed estimators.
