In this study, we propose exponential ratio estimators in the stratified two-phase sampling
utilizing an auxiliary attribute. The expressions for the mean squared error of these …

This paper suggests a new family of exponential estimators in the two-phase sampling using
the information of an auxiliary attribute. Theoretically, we obtain the mean square error …

In estimation theory, the use of auxiliary information significantly improves precision while
estimating population parameters. In this paper, an efficient class of ratio cum median …

In this study, we have considered stratified two-phase sampling scheme for estimating the
population mean of study variable taking auxiliary information. The proposed chain …

In this article, we propose an exponential estimator in the stratified random sampling taking
an auxiliary attribute. Expressions for MSE of the proposed estimators are derived up to first …

It is well known that the ratio and product estimators have the limitation of having efficiency
not exceeding that of the linear regression estimator. This paper develops a new approach …

En este artículo, de tipo exponencial generalizado ha sido propuesto con el fin de estimar la
varianza poblacional a través de una variables auxiliar en muestreo en dos fases. Algunos …

The present work suggests, some estimation procedures of population mean in two phase
sampling. Chain-type exponential dual to ratio and regression estimators have been …

North Eastern Regional Institute of Science and Technology Abstract-In this paper an
