A bivariate relative poverty line for leisure time and income poverty: Detecting intersectional differences using distributional copulas

open access: yesReview of Income and Wealth, Volume 70, Issue 2, Page 395-419, June 2024.
Empirical research on poverty today often goes beyond a focus on income to consider other dimensions of well‐being. However, relatively few multidimensional poverty measures explicitly consider time‐use, despite its particular relevance to women's double burden of paid and unpaid work.

Analytical Bayesian Copula‐Based Uncertainty Quantification (A‐BASIC‐UQ) Using Data with Missing Values in Structural Health Monitoring

open access: yesStructural Control and Health Monitoring, Volume 2024, Issue 1, 2024.
The presence of missing values is common in real‐world datasets, so modeling and uncertainty quantification (UQ) of incomplete datasets have gained increasing attention in various research areas, including structural health monitoring (SHM). However, modeling and UQ utilizing incomplete datasets are nontrivial tasks. On the other hand, prediction based

INDEXES TO MEASURE DEPENDENCE BETWEEN CLINICAL DIAGNOSTIC TESTS: A COMPARATIVE STUDY INDICES PARA MEDIR DEPENDENCIA ENTRE PRUEBAS PARA DIAGNÓSTICO CLÍNICO: UN ESTUDIO COMPARATIVO

open access: yesRevista Colombiana de Estadística, 2011
In many practical situations, clinical diagnostic procedures include two or more biological traits whose outcomes are expressed on a continuous scale and are then dichotomized using a cut point.

On a Perturbed Risk Model with Time‐Dependent Claim Sizes

open access: yesJournal of Mathematics, Volume 2024, Issue 1, 2024.
We consider a risk model perturbed by a Brownian motion, where the individual claim sizes are dependent on the inter‐claim times. We study the Gerber–Shiu functions when ruin is due to a claim or the jump‐diffusion process. Integro‐differential equations and Laplace transforms satisfied by the Gerber–Shiu functions are obtained.

Continuous Exchangeable Markov Chains, Idempotent and 1-Dependent Copulas

open access: yesMathematics
New copula families are constructed based on orthogonality in L2(0,1). Subclasses of idempotent copulas with square integrable densities are derived.

Farlie-Gumbel-Morgenstern bivariate log-normal: applications and comparison of semiparametric and parametric methods for estimating copulas

open access: yesKuwait Journal of Science
This study introduces the Farlie-Gumbel-Morgenstern bivariate log-normal (bivariate FGM-LN) distribution, which was created using the FGM copula to describe dependent skewed data.

Communications Performance Analysis of Wireless Multiple Access Channel With Specially Correlated Sources

open access: yesIEEE Access
From both practical and theoretical viewpoints, performance analysis of communication systems using information-theoretic results is very important. In this study, first, we obtain a general achievable rate for a two-user wireless multiple access channel

Analysis of Dependent Variables Following FGM Bivariate Generalized Burr Distribution Based on Economic Data [PDF]

open access: yesThe Egyptian Statistical Journal
The generalized Burr (GB) distribution is a flexible distribution that is used to describe many types of data. This distribution has a flexible hazard function, which can take a decreasing, approximately constant, or unimodal shape over time.
