Soil salinization is a land degradation process that leads to reduced agricultural yields. This
study investigated the method that can best predict electrical conductivity (EC) in dry soils …

Estimating the population mean is of prime concern in many studies, and calibrations are
popular choices. A robust calibration estimator estimates the mean using the minimum …

This paper introduces a new method to estimate the population variance of a study variable
in stratified successive sampling over two occasions, while accounting for random non …

A new calibration estimator is proposed to estimate the population mean in the stratified
random sampling. The corrected expression of Tracy et al.(2003) calibrated weights are …

Calibration method adjusts the original design weights to improve the estimates by using
auxiliary information. In this article we have proposed new calibration estimators under …

Calibration estimation improves the precision of the estimates of population parameters by
incorporating specified auxiliary information. A class of calibration estimators has been …

In recent years, calibration estimation has become an important field of research in survey
sampling. This paper proposes a new calibration estimator for the population mean in the …

It is well known that the ratio and product estimators have the limitation of having efficiency
not exceeding that of the linear regression estimator. This paper develops a new approach …

In this paper, a new improved calibration estimator for estimating the population mean in the
stratified random sampling using standard deviation of the auxiliary variable is proposed. A …
