Process monitoring through control charts is a quite popular practice in statistical process
control. From a statistical point of view, a superior control chart is the one which has an …

Our study explores neutrosophic statistics, an extension of classical and fuzzy statistics, to
address the challenges of data uncertainty. By leveraging accurate measurements of an …

In this paper, we consider chain ratio and regression type estimators for estimating median
in survey sampling. We find expressions for the variance of the chain-ratio and chain …

Present investigation deals with the problem of random non response in estimation of
population variance on current occasion in two-occasion successive sampling. To reduce …

This article suggests a generalized class of estimators for population median of the study
variable in simple random sampling using information on an auxiliary variable. Asymptotic …

To estimate the unknown population median, several researchers have developed efficient
estimators but these estimators are unable to provide efficient results in the existence of …

In successive sampling on two occasions the problem of estimating a finite population
quantile has been considered. The theory developed aims at providing the optimum …

A general family of estimators for estimating the population median is proposed by making
use of two auxiliary variables in two-phase sampling. Under simple random sampling …

The improved classes of difference-type estimators of finite population median by using
auxiliary information in simple random sampling and two-phase sampling have been …

This article considers some classes of estimators of the population median of the study
variable using information on an auxiliary variable with their properties under large sample …
