In this paper log transformation of modified ratio estimator of population mean when non-response error exists on both study variable and auxiliary variable was proposed. Using sub-sampling method of treating unit non-response, the properties of the proposed estimator as well as optimality conditions up to first order approximation were obtained. Theoretical and empirical comparison of the proposed estimator were carried out, comparing it with some existing estimators. The result of the theoretical comparison shows that the proposed estimator under optimum condition is more efficient than classical ratio estimator and Hansen and Hurwitz unbiased estimator. Furthermore, the empirical analysis on two different datasets revealed that the mean squared error of the proposed estimator increases as the value of λ increases. Also the percentage relative efficiency increases with the increase in the value of λ. The theoretical results are in consonant with the empirical results hence the proposed estimator is considered more efficient than classical ratio and Hansen and Hurwitz unbiased estimators in terms having lower mean squared error and more gain in efficiency under optimality condition in estimating population mean in the presence of non-response error and can be used in real life survey.
