Simulation Study of Ratio Type Estimators in Stratified Random Sampling Using Multi-Auxiliary Information
The paper addresses the problem of estimating the population mean of the study variable in stratified random sampling by using multi-auxiliary variable. In this paper, we proposed a ratio type estimator for estimating the population mean of the study variable by using multi-auxiliary variables. Stratified random sampling is taken into consideration. The expressions for the bias and mean square error (MSE) of the proposed estimator have been derived. The proposed estimator is compared with other existing estimators in terms of efficiency. An empirical study with the aid of simulation has also been carried out to validate the theoretical results obtained. The theoretical and empirical studies reveal that the proposed estimator performs better than existing estimators in the literature.
