Abstract
In the situation of non-response, we propose a class of exponential estimators for estimating the population mean. Two cases were studied, first case when the non-response occurs on both the study variable y and the auxiliary variable x and the population mean of the auxiliary variable is known and the second case is when the non-response occurs on the study variable y, information on the auxiliary variable x is obtained from all the sample units, and the population mean of the auxiliary variable x is known. The bias, MSE and minimum MSE are separately obtained for both the situations. We compare the proposed estimator theoretically and empirically with the existing estimators.
