Ratio estimators of population means using quartile function of auxiliary variable using double sampling [PDF]
Ratio estimators have been used in survey sampling for estimating population mean when the population mean of an auxiliary variable is known. However, as the auxiliary information is not always available we cannot gain any benefit from using ratio ...

A new exponential estimator for finite population mean under double sampling using one auxiliary variable [PDF]
This paper proposes an exponential estimator of a population mean under double sampling using one auxiliary variable. The proposed estimator is modified from the estimator of Khatua and Misha (2013) and Ozgul and Cingi (2014).

Use of an efficient unbiased estimator for finite population mean.
In this study, we propose an improved unbiased estimator in estimating the finite population mean using a single auxiliary variable and rank of the auxiliary variable by adopting the Hartley-Ross procedure when some parameters of the auxiliary variable ...

Separate and Combined Ratio Estimators for the Median [PDF]
In this paper, two methods for median estimation for stratified random sample are suggested. We had suggested two median estimators for stratified sample (Hussein 1999). The position and stratified estimators suggested earlier are applicable in situation

Scalar auxiliary variable approache for the surface quasi-geostrophic equation
We present a numerical method for approximating the two-dimensional surface quasi-geostrophic equation. We first reformulate the equation into an equivalent system by using the scalar auxiliary variable approach.

Estimation of Finite Population Ratio When Other Auxiliary Variables are Available in the Study
The estimation of the population total $t_y,$ by using one or more auxiliary variables, and the population ratio $\theta_{xy}=t_y/t_x,$ $t_x$ is the population total for the auxiliary variable $X$, for a finite population are heavily discussed in the ...
