Copula‐Based Cosimulation for Simulating Temporal or Spatial Data in Biogeosciences

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 130, Issue 10, October 2025.
Abstract Accurate modeling of dependencies between variables of interest is imperative for understanding biophysical processes and mechanisms relevant to biogeosciences research. This study presents copula‐based cosimulation (CopCoSim) as an approach to model the temporal or spatial joint distributions of multiple variables by capturing their ...

Multivariate modeling of flood characteristics using Vine copulas

open access: yesEnvironmental Earth Sciences, 2020
Vine copulas provide a great deal of flexibility in modeling complex dependence structures between the variables. In spite of its importance, very limited attention has been paid in hydrology field. In the present study, multivariate modelling of flood characteristics was performed using traditional Archimedean and Elliptical and Vine copulas.

Investigation on the Calibration of Numerical Models for Cast Steel Replaceable Modular Yielding Links in Steel Eccentrically Braced Frames

open access: yesEarthquake Engineering &Structural Dynamics, Volume 54, Issue 10, Page 2433-2452, August 2025.
ABSTRACT A new generation of yielding links, referred to as cast steel replaceable modular yielding links (CMLs), was recently validated through extensive large‐scale testing, to enhance the seismic performance of steel eccentrically braced frames (EBFs). The effective use of CMLs relies on accurately evaluating the seismic response of the EBF systems,

Seismic Reliability Analysis of Reinforced Concrete Arch Bridges Considering Component Correlation

open access: yesBuildings
To more effectively account for the correlation between components in the seismic reliability analysis of reinforced concrete arch bridges, this study proposes a system seismic reliability analysis method based on the D-vine Copula function. First, based

Tail Risk Hedging: The Superiority of the Naïve Hedging Strategy

open access: yesJournal of Futures Markets, Volume 45, Issue 8, Page 977-1005, August 2025.
ABSTRACT Mitigating extreme tail risk is essential for institutions and corporations to prevent financial losses from severe asset price fluctuations across many asset classes. This study shows that a simple futures hedging strategy, the naïve hedge, is remarkably effective at managing tail risk—so much so that few other methods can beat it.

D-Vine-Based Correction of Physics-Based Model Output for the Identification of Risky Flights With Respect to Runway Overruns

open access: yesIEEE Access
Flight dynamic-based physical models are employed to assess the risk of runway overruns, predicting risk based on the metric given by the distance to a controllable speed of 80 knots after landing.

Vine copulas structures modeling on Russian stock market

open access: yesDiscrete and Continuous Models and Applied Computational Science, 2019
Pair-copula constructions have proven to be a useful tool in statistical modeling, particularly in the field of finance. The copula-based approach can be used to choose a model that describes the dependence structure and marginal behaviour of the data in
