Study of Dual to Ratio-Cum-Product Estimator of Finite Population Mean under Double Sampling in Sample Surveys [PDF]

open access: yesJournal of Statistical Theory and Applications (JSTA), 2015
A class of estimator based on dual to ratio and dual to product-type estimator in double sampling for estimating finite population mean is proposed. The bias and mean square error of the proposed estimator are obtained in two different cases.

A Classification Bias and an Exclusion Bias Jointly Overinflated the Estimation of Publication Biases in Bilingualism Research

open access: yesBehavioral Sciences, 2023
A publication bias has been argued to affect the fate of results in bilingualism research. It was repeatedly suggested that studies presenting evidence for bilingual advantages are more likely to be published compared to studies that do not report results in favor of the bilingual advantage hypothesis.

Higher Order Bias Correcting Moment Equation for M-Estimation and Its Higher Order Efficiency

open access: yesEconometrics, 2016
This paper studies an alternative bias correction for the M-estimator, which is obtained by correcting the moment equations in the spirit of Firth (1993).

A new exponential estimator for finite population mean under double sampling using one auxiliary variable [PDF]

open access: yesSongklanakarin 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).

Direct Reduction of Bias of the Classical Hill Estimator

open access: yesRevstat Statistical Journal, 2005
In this paper we are interested in an adequate estimation of the dominant component of the bias of Hill’s estimator of a positive tail index γ, in order to remove it from the classical Hill estimator in different asymptotically equivalent ways.

Reducing effects of dispersal on the bias of 2-sample mark-recapture estimators of stream fish abundance. [PDF]

open access: yesPLoS ONE, 2018
The 2-sample mark-recapture method with Chapman's estimator is often used by inland fishery managers to estimate the reach-scale abundance of stream fish.

Generalized Sum Plots

open access: yesRevstat Statistical Journal, 2011
Sousa and Michailidis (2004) developed the sum plot based on the Hill (1975) estimator as a diagnostic tool for selecting the optimal k when the distribution is heavy tailed.

Photo-$z$ estimation: An example of nonparametric conditional density estimation under selection bias

open access: yesThe Annals of Applied Statistics, 2017
Redshift is a key quantity for inferring cosmological model parameters. In photometric redshift estimation, cosmologists use the coarse data collected from the vast majority of galaxies to predict the redshift of individual galaxies. To properly quantify the uncertainty in the predictions, however, one needs to go beyond standard regression and instead

Improved estimation of population proportion possessing sensitive attribute with unknown repeated trials in randomized response sampling

open access: yesStatistica, 2007
This paper proposes an estimator for population proportion p possessing sensitive attribute under unknown repeated trials model envisaged by Singh and Joarder (1997). The exact bias and mean square error of the proposed estimators are worked out.

Assessment of sample frequency bias and precision in fluvial flux calculations – An improved low bias estimation method [PDF]

open access: yesJournal of Hydrology, 2013
Summary Despite the importance of calculating the flux of solutes and particulates through the global fluvial network the number of studies that have considered the bias and precision of any method is limited. Furthermore, no study has, on the basis of the bias of the method, proposed new methods with a lower bias nor considered the implications of ...
