Separate and Combined Ratio Estimators for the Median [PDF]
The Egyptian Statistical Journal, 1999 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
Journal of Algorithms & Computational Technology, 2023 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.

Classes of combined population mean estimators utilizing transformed variables under double sampling with application to air pollution in Chiang Rai, Thailand [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2022 The transformation method can be used to increase the efficiency of the variable of interest for estimating population mean. Two classes of combined population mean estimators utilizing transformation on an auxiliary variable and on both an auxiliary ...

Estimation of Finite Population Ratio When Other Auxiliary Variables are Available in the Study
Austrian Journal of Statistics, 2014 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 ...

Multiple Auxiliary Variables in Nonresponse Adjustment
Sociological Methods & Research, 2011 Prior work has shown that effective survey nonresponse adjustment variables should be highly correlated with both the propensity to respond to a survey and the survey variables of interest. In practice, propensity models are often used for nonresponse adjustment with multiple auxiliary variables as predictors.

Effective Auxiliary Variables via Structured Reencoding
CoRR, 2023 Extended resolution shows that auxiliary variables are very powerful in theory. However, attempts to exploit this potential in practice have had limited success. One reasonably effective method in this regard is bounded variable addition (BVA), which automatically reencodes formulas by introducing new variables and eliminating clauses, often ...

A Class of Exponential Regression Type Estimators for Population Variance in Two-Phase Sampling [PDF]
Journal of Statistical Theory and Applications (JSTA), 2017 This article deals with the problems of efficient estimation of population variance in two-phase (double) sampling. Using information on two auxiliary variables, a class of chain exponential to regression type estimators has been proposed and its ...
