The presence of dispersion/variability in any process is understood and its careful
monitoring may furnish the performance of any process. The interquartile range (IQR) is one …

Due to the progressive increase in development of desert land in Egypt, the demand for
efficient and accurate land cover change information is increasing. In this study, we apply …

Standard Shewhart control charts are often based on the assumption that the observations
follow a specific parametric distribution, such as the normal, and outlier-free samples are …

In this article, we propose naïve estimator, ratio estimator, and difference estimator of the
mode of a study variable by using the known mode of an auxiliary variable. The asymptotic …

Due to the progressive increase in population, sustainable development of desert land in
Egypt has become a strategic priority in order to meet the increasing demands of a growing …

The estimation of quantiles in the presence of auxiliary information is discussed. Calibration
and poststratification techniques provide simple and practical procedures for incorporating …

This paper presents some chain ratio-type estimators for estimating finite population
variance using two auxiliary variables in two phase sampling set up. The expressions for …

We consider a truncated Midzuno–Sen sampling scheme. The proposed method can be
used to estimate the distribution function of a study variable assuming that the distribution …

In this paper, we propose a transformed na\" ive ratio and product based estimators using
the characterizing scalar in presence of auxiliary information of the study variable for …

In this article, we consider the problem of estimation of mode using two-phase sampling.
Ratio-and difference-type estimators in two-phase sampling are proposed. The asymptotic …
