Non‐parametric Estimation of Tail Dependence
Scandinavian Journal of Statistics, 2006Abstract. Dependencies between extreme events (extremal dependencies) are attracting an increasing attention in modern risk management. In practice, the concept of tail dependence represents the current standard to describe the amount of extremal dependence.

DETECTING AND MODELING TAIL DEPENDENCE
International Journal of Theoretical and Applied Finance, 2004The aim of this work is to develop a nonparametric tool for detecting dependence in the tails of financial data. We provide a simple method to locate and measure serial dependence in the tails, based on runs tests. Our empirical investigations on many financial time series reveal a strong departure from independence for daily logreturns, which is not ...

Tail-weighted dependence measures with limit being the tail dependence coefficient
Journal of Nonparametric Statistics, 2017For bivariate continuous data, measures of monotonic dependence are based on the rank transformations of the two variables.

The simple econometrics of tail dependence
Economics Letters, 2011The aim of this paper is to show that measures on tail dependence can be estimated in a convenient way by regression analysis. This yields the same estimates as the non-parametric method within the multivariate Extreme Value Theory framework. The advantage of the regression approach is contained by its straightforward extension to the estimation of ...

Limiting Tail Dependence Copulas
Communications in Statistics - Theory and Methods, 2009The limiting lower-tail dependence copula (LLTDC) is defined as the copula of random variables which are right-truncated at thresholds tending to their left endpoints. This article shows LLTDCs are truncation-invariant and belong to the Ahmadi-Clayton family.

Estimating Tail Dependence of Elliptical Distributions
2006Recently there has been an increasing interest in applying elliptical distributions to risk management. Under weak conditions, Hult and Lindskog (2002) showed that a random vector with an elliptical distribution is in the domain of attraction of a multivariate extreme value distribution.

Mesomorphism dependence on heterocyclic tail
Molecular Crystals and Liquid Crystals, 2016ABSTRACTA novel homologous series of liquid crystal materials containing a heterocyclic ring was synthesized with a view to understanding and establishing the relation between liquid crystal (LC) properties and a molecular structure; and with a view to curing skin-related diseases following biological activity studies.
