Confidence Regions Based on Likelihood Ratio in a Nonlinear Model

open access: yes, 2015
[[abstract]]This paper is concerned with the confidence regions based on likelihood ratio in a nonlinear model. The quartic approximation of the coverage probability of the confidence regions is derived for the two-parameter nonlinear model.

RIS-Assisted Terahertz Clustered HetNets: Coverage and Rate Analysis

open access: yesIEEE Open Journal of the Communications Society
Terahertz (THz) transmission technologies hold significant potential for enabling ultra-broadband in next-generation networks. Despite the vast bandwidth offered by the THz, it faces significant challenges stemming from its limited transmission range.

On Bootstrap Coverage Probability with Dependent Data [PDF]

open access: yes, 2003
This paper establishes the optimal bootstrap block lengths for coverage probabilities when the bootstrap is applied to covariance stationary ergodic dependent data. It is shown that the block lengths that minimize the error in coverage probabilities of one- and two-sided block bootstrap confidence intervals of normalized and studentized smooth ...

Cumulative Social Disadvantage and Disease Activity in Juvenile Idiopathic Arthritis: A Childhood Arthritis and Rheumatology Research Alliance Registry Study

open access: yesArthritis Care &Research, EarlyView.
Objective Social determinants of health (SDOH) contribute to juvenile idiopathic arthritis (JIA) disparities, but most studies have assessed SDOH independently rather than cumulatively across individual, family, and neighborhood levels. Using a socioecological framework, we investigated the relationship among cumulative social disadvantage ...

Global, regional, and national trends in routine childhood vaccination coverage from 1980 to 2023 with forecasts to 2030: a systematic analysis for the Global Burden of Disease Study 2023.

open access: yes
Background: Since its inception in 1974, the Essential Programme on Immunization (EPI) has achieved remarkable success, averting the deaths of an estimated 154 million children worldwide through routine childhood vaccination. However, more recent decades

Simulation comparison of modified confidence intervals based on robust estimators for coefficient of variation: skewed distributions case with real applications

open access: yesArab Journal of Basic and Applied Sciences
In this article, we propose confidence intervals for the population coefficient of variation based on some robust estimators such as trimmed mean, winsorized mean, Hodges-Lehmann estimator and trimean.

Neighborhood Socioeconomic Status and Short‐Term Functional Outcomes in Systemic Lupus Erythematosus

open access: yesArthritis Care &Research, EarlyView.
Objective Individuals with systemic lupus erythematosus (SLE) can accumulate functional status (FS) impairment. We evaluated the association between neighborhood socioeconomic disadvantage, as measured by the Area Deprivation Index (ADI), and FS in a national SLE sample.

Health Care Use Among Patients Presenting to Emergency Department for Gout Flares in Ontario, Canada: A Population‐Based Health Systems Analysis

open access: yesArthritis Care &Research, EarlyView.
Objective We characterized emergency department (ED) gout visits and identified patient characteristics and health services patterns contributing to ED presentations. Methods We conducted a population‐based study of ED gout visits in Ontario, Canada, between 2014 and 2023.
