Modified Ratio Estimator in Survey Sampling using a linear combination



Author(s): TA Raja, S Maqbool, FJ Wani

Abstract:

A new modified ratio estimator of population mean of the main variable by means of the linear combination of known values of Co-efficient of Kurtosis and Tri-Mean of the auxiliary variable has been worked out. Mean Square Error (MSE) and Bias of the proposed estimator is calculated and compared with Yan & Tian (2010) estimator. The comparison is demonstrated theoretically and illustrated practically and the conclusion is drawn that the proposed estimator is performing deftly with the above existing estimator.


Keywords: Estimator, Auxiliary variable, Mean square error, Bias, Co-efficient of Kurtosis, Tri-Mean
