Generalized Exponential Methods of Imputation in Estimation of Current Population Mean in Two-Occasion Successive Sampling

M. Khetan, G. N. Singh, Prashant Verma


In this paper, we have proposed generalized exponential imputation methods to handle with the problems of non-response when it occurs on both occasions in two-occasion successive sampling. The Suggested imputation methods result in generalized exponential estimators of current population mean in two-occasion successive sampling. Properties of the estimators have been examined and their efficiency is shown through empirical means of comparison. Suitable recommendations have been put forward for survey practitioners.


Non-response, successive sampling, imputation, optimum replacement strategy.
