This paper considers some efficient combined and separate classes of estimators of the
population mean in the presence of bivariate auxiliary information under stratified ranked set …

In this paper, we propose the exponential ratio-type estimator for the elevated estimation of
population mean, implying one auxiliary variable in stratified random sampling using the …

This manuscript considers some improved combined and separate classes of estimators of
population mean using bivariate auxiliary information under stratified simple random …

In this paper we have suggested a generalized class of estimators for estimating the finite
population mean ˉY of the study variable y using information on two auxiliary variables x …

This paper proposes a class of estimators based on information of two auxiliary variables.
The expressions of mean square errors of the proposed class of estimators are derived in a …

Improvement in the estimation of population mean has been an area of interest in sampling
theory. So many estimators have been suggested for elevated estimation of the population …

Monitoring of process parameters via control charts is exceptionally common exercise in
statistical process control (SPC). The exponentially weighted moving average (EWMA) …

Control charts are commonly used tools in statistical process control for the detection of
shifts in process parameters. Shewhart-type charts are efficient for large shift values …

This paper addresses the problem of an alternative approach to estimating the population
mean of the study variable with the help of the auxiliary variable under stratified random …

The distribution function (DF) is a determinant functional parameter in many academic
disciplines that use probability tools for data analysis, such as economics and medicine …
