A New Ratio Estimator in Stratified Random Sampling

Hartley-Ross type unbiased estimators using the Stratified Random Sampling

“…In this article, we study on the estimators given by Kadilar and Cingi [5], [6] to obtain the unbiased estimation of the population mean in the stratified random sampling. Both the theoretical and empirical results show that the suggested unbiased estimators have smaller variance values than the compared estimators under the determined conditions.…”

“…Secondly, comparing the variance of the proposed estimator in (2.7) with the MSE of the estimators given in Kadilar and Cingi [6], we have…”

“…We improve Hartley-Ross estimators using the proposed estimators by Kadilar and Cingi [5], [6] with their unbiased biases, and in this way, we obtain the following estimators:…”

“…We propose a class of unbiased estimators using the estimators in Kadilar and Cingi [5], [6]. We derive the variance equations, up to the first degree of approximation, for all proposed estimators.…”

“…Kadilar and Cingi [5], [6] define some estimators using the coefficient of kurtosis (β 2 ) and the coefficient of variation (C x ) of the auxiliary variable under the stratified random sampling as…”
