A Statistical Model for Analyzing Interdependent Complex of Plant Pathogens Un modelo estadístico para analizar complejos interdependientes de patógenos vegetales

Revista Colombiana de Estadística, 2012
We introduce a new approach for modeling multivariate overdispersed binomial data, from a plant pathogen complex. After recalling some theoretical foundations of generalized linear models (GLMs) and Copula functions, we show how the later can be used to ...

Gaussian copula–Bayesian dynamic linear model–based time-dependent reliability prediction of bridge structures considering nonlinear correlation between failure modes

Advances in Mechanical Engineering, 2016
Bridge structures in service are subjected to long-term ambient environments and continuously increasing traffic demands; therefore, the physical quantities of the existing bridge structures are subjected to changes in both time and space. Through health

A Copula Discretization of Time Series-Type Model for Examining Climate Data

Mathematics
The study presents a comparative analysis of climate data under two scenarios: a Gaussian copula marginal regression model for count time series data and a copula-based bivariate count time series model.

ESTIMASI NILAI CONDITIONAL VALUE AT RISK MENGGUNAKAN FUNGSI GAUSSIAN COPULA

E-Jurnal Matematika, 2015
Copula is already widely used in financial assets, especially in risk management. It is due to the ability of copula, to capture the nonlinear dependence structure on multivariate assets.

A Copula-Based Scenario Generation Method for Renewable Wind Power Outputs of Two Wind Farms

Energies
Renewable wind power output is characterized by strong randomness, volatility, and spatial dependence, which makes accurate two-adjacent wind farm scenario generation essential for stochastic dispatch and secure operation of power systems.

Portfolio Risk and Dependence Modeling: Application of Factor and Copula Models

The International Journal of Banking and Finance, 2012
We consider portfolio credit risk modeling with a focus on two approaches, the factor model, and the copula model. While other models have received greater scrutiny, both factor and cupola models have received little attention although these are ...
