Calibrating and Simulating Copula Functions in Financial Applications
Frontiers in Applied Mathematics and Statistics, 2021 Copula functions can be utilized in financial applications to determine the dependence structure of the financial asset returns in the portfolio. Empirical evidence has proved the inadequacy of the multi-normal distribution, traditionally adopted to ...

A Class of Copula-Based Bivariate Poisson Time Series Models with Applications
Computation, 2021 A class of bivariate integer-valued time series models was constructed via copula theory. Each series follows a Markov chain with the serial dependence captured using copula-based transition probabilities from the Poisson and the zero-inflated Poisson ...

Bivariate Flood Frequency Analysis Using the Copula Archimedean Function (Gumbel–Hougaard) [PDF]
پژوهشهای آبخیزداری, 2020 Flood is a multivariate and complex phenomenon that has a random nature. In conventional methods of flood frequency analysis, only flood peak variable is important and it is assumed that the variable under consideration follows a particular parametric ...

Nested Copula Model for Overall Seismic Vulnerability Analysis of Multispan Bridges
Shock and Vibration, 2022 Piers and bearings influence each other in earthquakes, and the failure of any component will affect the whole function of bridges. Thus, it is critical to consider the correlations between multiple components in the seismic vulnerability analysis of the

Flood routing via a copula-based approach
Hydrology Research, 2021 Floods are among the most common natural disasters that if not controlled may cause severe damage and high costs. Flood control and management can be done using structural measures that should be designed based on the flood design studies. The simulation

A Novel Nonparametric Estimation for Conditional Copula Functions Based on Bayes Theorem
IEEE Access, 2019 Conditional copula which measures the conditional dependence among variables, possesses a special position in copula field. In this article, based on Bayes theorem, we derive three kinds of conditional copula functions as the product of the corresponding
