Copula-Based Risk Modeling: A Comparative Analysis of MCAViaR and Gaussian Copulas for Global Indices [PDF]

open access: yesMathematics and Modeling in Finance
This study comparatively analyzes two advanced financial risk modeling frameworks: a copula-based Value-at-Risk (VaR) approach and the Multivariate Conditional Autoregressive Value-at-Risk (MCAViaR) model.

A New Log-Logistic Lifetime Model with Mathematical Properties, Copula, Modified Goodness-of-Fit Test for Validation and Real Data Modeling

open access: yesMathematics, 2020
After defining a new log-logistic model and studying its properties, some new bivariate type versions using “Farlie-Gumbel-Morgenstern Copula”, “modified Farlie-Gumbel-Morgenstern Copula”, “Clayton Copula”, and “Renyi’s entropy Copula” are derived. Then,

The Bivariate Defective Gompertz Distribution Based on Clayton Copula with Applications to Medical Data

open access: yesAustrian Journal of Statistics, 2022
In medical studies, it is common the presence of a fraction of patients who do not experience the event of interest. These patients are people who are not at risk of the event or are patients who were cured during the research. The proportion of immune or cured patients is known in the literature as cure rate.

Copula families used in the mixture models in our framework. [PDF]

open access: yes, 2022
Each panel shows a scatter plot of samples drawn from a parametric copula family (named in the title of each plot) with a fixed parameter θ (shown in the bottom right corner). In total, we used 10 different copula elements—Gaussian + Frank + 4 × Clayton +

BHF and copula models in small area estimation for household per capita expenditure in Bogor District

open access: yesJurnal Natural
Small area statistics are required when the sample size is small to produce estimates with adequate precision. The assumptions underlying Battese Harter Fuller (BHF) unit-level models may often be unrealistic in some applications.
