A Note on Kumar (2016): Improved Estimation of Population Mean in the Presence of Measurement Error and Non-response

Kumar (J Stat Theory Pract 10(4):707–720, 2016) introduced an estimator for mean in the presence of non-response and measurement error. However, the mean square error (MSE) and the minimum MSE expressions presented in that paper need some corrections and simulation results need to be examined in the light of this correction. Simulations results show that with the corrected MSE expression, the Kumar estimator performs better than some of existing estimators, which could not be claimed with the original MSE expressions.
