Hierarchical Bayesian Modeling and Randomized Response Method for Inferring the Sensitive-Nature Proportion

Mathematics, 2021
In this study, a new three-statement randomized response estimation method is proposed to improve the drawback that the maximum likelihood estimation method could generate a negative value to estimate the sensitive-nature proportion (SNP) when its true ...

Optimal rates of convergence for estimating the null density and proportion of nonnull effects in large-scale multiple testing [PDF]

, 2010
An important estimation problem that is closely related to large-scale multiple testing is that of estimating the null density and the proportion of nonnull effects.

Protocol to estimate cell type proportions from bulk RNA-seq using DAISM-DNNXMBD

STAR Protocols, 2022
Summary: Computational protocols for cell type deconvolution from bulk RNA-seq data have been used to understand cellular heterogeneity in disease-related samples, but their performance can be impacted by batch effect among datasets.

A simulation study: An enhanced generalized class of estimators for estimation of population proportion using twofold auxiliary attribute

Heliyon, 2023
The article introduces a novel class of estimators designed for estimating finite population proportions. These estimators utilize dual auxiliary attributes and are applicable under simple random sampling.

An integration of competing accounts on children’s number line estimation

Frontiers in Psychology, 2015
Children’s estimation patterns in bounded number line estimation reveal marked developmental changes. Three different theoretical accounts were proposed to explain these changes: a log-to-linear shift account, a proportion-judgment account and a two ...

Bayesian sequential estimation of the proportion of damage in maize seeds

Scientia Agricola
Sampling is an essential step in estimating a parameter: thus, cost and time associated to this step should be minimized. Sequential sampling is characterized by using samples of variable sizes given as a function of observations, and sequential sampling

The Development of Symbolic and Non-Symbolic Number Line Estimations: Three Developmental Accounts Contrasted Within Cross-Sectional and Longitudinal Data

Psychologica Belgica, 2016
Three theoretical accounts have been put forward for the development of children’s response patterns on number line estimation tasks: the log-to-linear representational shift, the two-linear-to-linear transformation and the proportion judgment account ...

A simulation study of regression approaches for estimating risk ratios in the presence of multiple confounders

Emerging Themes in Epidemiology, 2021
Background Risk ratio is a popular effect measure in epidemiological research. Although previous research has suggested that logistic regression may provide biased odds ratio estimates when the number of events is small and there are multiple confounders,
