In this paper, two modified, design-based calibration ratio-type estimators are presented.
The suggested estimators were developed under stratified random sampling using …

We consider the problem of the estimation of the population mean of a study variable by
assuming that the population means of an auxiliary variable are known at both stages of …

SUMMARY The Calibration Approach proposed by Deville and Särndal (1992) is a popular
technique to efficiently use auxiliary information in survey sampling. In this study, calibration …

In the present article, an effort has been made to develop calibration estimators of the
population mean under two-stage stratified random sampling design when auxiliary …

To avoid the environmental pollution caused by livestock manure and provide rational layout
of livestock farm, we estimated the livestock manure phosphorus load by the excretion …

In many agricultural, forestry, environmental, and ecological surveys, data are often spatial
in nature and exhibit spatial nonstationarity. A well-known method for addressing spatial …

The calibration approach is a popular technique for incorporating auxiliary information for
estimation of population parameters in survey sampling. In general, the Calibration …

Estimation of major crop yield rates at the district level using calibration estimation technique
is reported here when auxiliary information is available at the unit level only for the selected …

Auxiliary information is often used to improve the precision of estimators of finite population
total. Calibration approach is widely used for making efficient use of auxiliary information in …

Most common methods of estimation where the auxiliary information are used ratio,
