One of the disadvantages of the point estimate in survey sampling is that it fluctuates from
sample to sample due to sampling error, as the estimator only provides a point value for the …

In this article, we proposed an improved finite population variance estimator based on
simple random sampling using dual auxiliary information. Mathematical expressions of the …

In some instances, the size of the target population might exhibit significant variation. In the
medical investigation, the number of individuals troubled with a certain infection and the …

Robust regression tools are commonly used to develop regression‐type ratio estimators with
traditional measures of location whenever data are contaminated with outliers. Recently, the …

This manuscript proffers a new efficient class of estimators for population mean in two-phase
sampling using the known population proportion. The usual mean estimator, classical ratio …

In survey sampling, several estimation procedures have been proffered by various
prominent authors to compute the impact of measurement errors (ME) but the impact of …

The extended exponential weighted moving average (EEWMA) statistic is a memory type
statistic that uses past observations along with the current information for the estimation of a …

Advancements in sensor technology have brought a revolution in data generation.
Therefore, the study variable and several linearly related auxiliary variables are recorded …

Human-assisted surveys, such as medical and social science surveys, are frequently
plagued by non-response or missing observations. Several authors have devised different …

This research introduces a novel sub-estimator designed to estimate the population mean
under ranked set sampling, motivated by the new concept of a recently introduced sub-ratio …
