A new ratio type estimator for computation of population mean under post-stratification

Abstract

In this study, the difficulty of estimating the population mean in the situation of post-stratification is discussed. The case of post-stratification is presented for ratio-type exponential estimators of finite population mean. Mean-squared error of the proposed estimator is obtained up to the first degree of approximation. In the instance of post-stratification, the proposed estimator was compared with the existing estimators. An empirical study by using some real data and further, simulation study has been carried out to demonstrate the performance of the proposed estimator.

Efficient Predictive Estimator for Finite Population Mean Using Supplementary Variable Under Post Stratification

“…In the area of post stratification, contributions have been made by Jagers et al [4], Jagers [5], Agrawaland Panda [6], and Singh and Ruiz Espezo [7]. The characteristics of the post stratification product and ratio type exponential estimators by Bahl and Tuteja [8] and Tailor et al [9] were recently specified by Rather et al [10].…”
