Asymptotic properties of the Bernstein density copula for dependent data [PDF]

open access: yes
Copulas are extensively used for dependence modeling. In many cases the data does not reveal how the dependence can be modeled using a particular parametric copula. Nonparametric copulas do not share this problem since they are entirely data based.

Copula–entropy theory for multivariate stochastic modeling in water engineering

open access: yesGeoscience Letters, 2018
The copula–entropy theory combines the entropy theory and the copula theory. The entropy theory has been extensively applied to derive the most probable univariate distribution subject to specified constraints by applying the principle of maximum entropy.

Copula bivariate probit models: with an application to medical expenditures [PDF]

open access: yes
The bivariate probit model is frequently used for estimating the effect of an endogenous binary regressor (the "treatment") on a binary health outcome variable.

False discovery rate control under Archimedean Copula [PDF]

open access: yes, 2013
We are considered with the false discovery rate (FDR) of the linear step-up test φLSU considered by Benjamini and Hochberg (1995). It is well known that φLSU controls the FDR at level m0q/m if the joint distribution of p-values is multivariate totally ...

Dynamic dependence ordering for Archimedean copulas and distorted copulas

open access: yesKybernetika, 2008
This paper proposes a general framework to compare the strength of the dependence in survival models, as time changes, i.e. given remaining lifetimes , to compare the dependence of given >t, and given >s, where s>t. More precisely, analytical results will be obtained in the case the survival copula of is either Archimedean or a distorted copula.

Bounds for the Clayton copula

open access: yesNonlinear Analysis, 2017
We provide two upper bounds on the Clayton copula Cθ(u1,...,un) if θ > 0 and n ≥ 2 and a lower bound in the case θ ∈ [-1,0) and n ≥ 2. The obtained bounds provide a nice probabilistic interpretation related to some negative dependence structures and also

Some applications of the Archimedean copulas in the proof of the almost sure central limit theorem for ordinary maxima

open access: yesOpen Mathematics, 2017
Our goal is to state and prove the almost sure central limit theorem for maxima (Mn) of X1, X2, ..., Xn, n ∈ ℕ, where (Xi) forms a stochastic process of identically distributed r.v.’s of the continuous type, such that, for any fixed n, the family of r.v.’

Systemic Weather Risk and Crop Insurance: The Case of China [PDF]

open access: yes
The supply of affordable crop insurance is hampered by the existence of systemic weather risk which results in large risk premiums. In this article, we assess the systemic nature of weather risk for 17 agricultural production regions in China and explore
