Ratio estimators of population means using quartile function of auxiliary variable using double sampling [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2019 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 ...

Improved Estimators for Estimating Average Yield Using Auxiliary Variable [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2019 In this paper, we consider the improved estimation of average production of peppermint at block level of Barabanki district of Uttar Pradesh State (India). We suggest certain estimators for population-mean.

Auxiliary Variable Based Particle Filters [PDF]
, 2001 We model a time series {y t , t = 1, ..., n} using a state-space framework with the {y t |α t } being independent and with the state {α t } assumed to be Markovian. The task will be to use simulation to estimate f(α t |F t ), t = 1, ..., n, where F t is contemporaneously available information.

Restructured searls family of estimators of population mean in the presence of nonresponse
Frontiers in Applied Mathematics and Statistics, 2022 Nonresponse is a major problem encountered by surveyors when conducting sampling surveys. The present study suggested a naïve modified Searls method for the elevated estimation of the population mean of the primary variable under investigation by ...

High-redshift cosmography: auxiliary variables versus Padé polynomials [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT Cosmography becomes non-predictive when cosmic data span beyond the redshift limit z ≃ 1. This leads to a strong convergence issue that jeopardizes its viability. In this work, we critically compare the two main solutions of the convergence problem, i.e.

Use of an efficient unbiased estimator for finite population mean.
PLoS ONE, 2022 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 ...

On Lossless Coding With Coded Side Information [PDF]
, 2009 This paper considers the problem, first introduced by Ahlswede and Korner in 1975, of lossless source coding with coded side information. Specifically, let X and Y be two random variables such that X is desired losslessly at the decoder while Y serves as

A new exponential estimator for finite population mean under double sampling using one auxiliary variable [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2019 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).
