Estimating the Reciprocal of a Binomial Proportion

open access: yesInternational Statistical Review, 2023
SummaryThe binomial proportion is a classic parameter with many applications and has also been extensively studied in the literature. By contrast, the reciprocal of the binomial proportion, or the inverse proportion, is often overlooked, even though it also plays an important role in various fields.

Quantitative analysis of the impact of various urban socioeconomic indicators on search-engine-based estimation of COVID-19 prevalence

open access: yesInfectious Disease Modelling, 2022
Numerous studies have proposed search engine-based estimation of COVID-19 prevalence during the COVID-19 pandemic; however, their estimation models do not consider the impact of various urban socioeconomic indicators (USIs).

Estimation of Some Proportion in a Clustered Population

open access: yesNonlinear Analysis, 2009
The aim of this paper is to show that the traditional design-based estimator for the proportion of population units, associated with at least one subunit having an attribute of interest using the two-stage sampling design, is biased.

Variance estimation for a low-income proportion [PDF]

open access: yes, 2003
Proportions below a given fraction of a quantile of an income distribution are often estimated from survey data in poverty comparisons. We consider the estimation of the variance of such a proportion, estimated from Family Expenditure Survey data.

Estimation of a Finite Population Proportion in Light of Randomized Reporting

open access: yesJournal of Statistical Theory and Applications (JSTA), 2018
In large scale surveys, it is customary to accept unaltered the responses provided by the respondents, leaving no provision for investigators to pass on any circumstantial judgment on the responses.

The Impact of Imposing Equality Constraints on Residual Variances Across Classes in Regression Mixture Models

open access: yesFrontiers in Psychology, 2022
The purpose of this study is to explore the impact of constraining class-specific residual variances to be equal by examining and comparing the parameter estimation of a free model and a constrained model under various conditions.

Estimation of the proportion of genetic variance explained by molecular markers

open access: yesGenetics and Molecular Biology, 1998
Estimation of the proportion of genetic variance explained by molecular markers (p) plays an important role in basic studies of quantitative traits, as well as in marker-assisted selection (MAS), if the selection index proposed by Lande and Thompson ...

Efficient Nonparametric Estimation of Mixture Proportions

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1984
SUMMARY By constructing a sequence of multinomial approximations and related maximum likelihood estimators, we derive a Cramér-Rao lower bound for nonparametric estimators of the mixture proportions and thereby characterize asymptotically optimal estimators.

A Thermodynamic Method for the Estimation of Free Gas Proportion in Depressurization Production of Natural Gas Hydrate

open access: yesFrontiers in Earth Science, 2022
Free gas saturation is one of the key factors that affect the overall production behaviors of hydrate reservoirs. For example, different free gas contents could alter the thermal response of hydrate reservoirs to the artificial stimulation and hence ...

An alternative to Kim and Warde’s mixed randomized response technique

open access: yesStatistica, 2014
The paper proposes two mixed randomized response techniques as an alternative to the Kim and Warde’s (2005) randomized response technique. The properties of the models have been studied and found that the proposed mixed randomized response models are ...
