Improved Exponential Type Ratio Estimator ofPopulation Variance [PDF]

Revista Colombiana de Estadística, 2013
\noindent This article considers the problem of estimating the population variance using auxiliary information. An improved version of Singhs exponential type ratio estimator has been proposed and its properties have been studied under large sample ...

An Alternative Ratio-cum-Product Estimator of Population Mean Using a Coefficient of Kurtosis for Two Auxiliary Variates [PDF]

Data Science Journal, 2010
An alternative ratio-cum-product estimator of population mean using the coefficient of kurtosis for two auxiliary variates has been proposed. The proposed estimator has been compared with a simple mean estimator, the usual ratio estimator, a product ...

A new exponential ratio-type estimator with linear combination of two auxiliary variables. [PDF]

PLoS ONE, 2014
In sample surveys, it is usual to make use of auxiliary information to increase the precision of estimators. We propose a new exponential ratio-type estimator of a finite population mean using linear combination of two auxiliary variables and obtain mean

Estimating the Ratio of Means

WSEAS TRANSACTIONS ON MATHEMATICS, 2020
Confidence intervals for ratio of means for large paired and unpaired samples with finite variance,obtained by applying the central limit theorem and Cramér-Wold device, are given. Also, these intervals for ratiosare obtained under infinite variance and when considering independent populations, by using stable distributions.Numerical illustrations by ...

Estimation of a Ratio in the Finite Population [PDF]

Informatica, 2005
Summary: Estimation of the ratio of two totals is considered, when a probability sample from the finite population is available. Four estimators of the ratio are examined. The first one -- called ``simple'' -- is the ratio of the Horvitz-Thompson estimators of totals; the second -- the ratio of two ratio estimators of totals; the third one -- the ratio

A Two Parameter Ratio-Product-Ratio Estimator in Post Stratification

, 2022
In this paper we consider a two parameter ratio-product-ratio estimator for estimating population mean in case of post stratification following the estimator due to Chami et al (2012). The bias and mean squared error of proposed estimator are obtained to
