This study considers the issue of estimating the population variance utilizing trace of kernel
matrix in absence of non-response under simple random sampling scheme. Further …

This paper addresses the problem of estimating the population variance of the study
variable y using information on coefficient of variation Cx of an auxiliary variable x. We have …

In many sampling situations, researchers come across variety of data. These data are
largely affected by the parent distribution. There are characteristics which some data share …

In this paper, some ratio-type estimators for finite population variance have been proposed
using known values of the parameters of an auxiliary variable such as quartiles and their …

Sampling is one of the most important statistical techniques used to draw the inference
about the whole population when it is very large and researchers have limited resources in …
