On the tail dependence in bivariate hydrological frequency analysis

open access: yesDependence Modeling, 2015
In Bivariate Frequency Analysis (BFA) of hydrological events, the study and quantification of the dependence between several variables of interest is commonly carried out through Pearson’s correlation (r), Kendall’s tau (τ) or Spearman’s rho (ρ).

An Analysis of a Heuristic Procedure to Evaluate Tail (in)dependence

open access: yesJournal of Probability and Statistics, 2014
Measuring tail dependence is an important issue in many applied sciences in order to quantify the risk of simultaneous extreme events. A usual measure is given by the tail dependence coefficient.

Power-Law Distributions from Sigma-Pi Structure of Sums of Random Multiplicative Processes

open access: yesEntropy, 2017
We introduce a simple growth model in which the sizes of entities evolve as multiplicative random processes that start at different times. A novel aspect we examine is the dependence among entities.

Robust Learning of Tail Dependence

open access: yesEconometrics
Accurate estimation of tail dependence is difficult due to model misspecification and data contamination. This paper introduces a class of minimum f-divergence estimators for the tail dependence coefficient that unifies robust estimation with extreme ...

On Conditional Value at Risk (CoVaR) for tail-dependent copulas

open access: yesDependence Modeling, 2017
The paper deals with Conditional Value at Risk (CoVaR) for copulas with nontrivial tail dependence. We show that both in the standard and the modified settings, the tail dependence function determines the limiting properties of CoVaR as the conditioning ...

Lifestyle Behaviors and Cardiotoxic Treatment Risks in Adult Childhood Cancer Survivors

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Higher doses of anthracyclines and heart‐relevant radiotherapy increase cardiovascular disease (CVD) risk. This study assessed CVD and CVD risk factors among adult childhood cancer survivors (CCSs) across cardiotoxic treatment risk groups and examined associations between lifestyle behaviors and treatment risks.

Bivariate Extreme Statistics, II

open access: yesRevstat Statistical Journal, 2012
We review the current state of statistical modeling of asymptotically independent data. Our discussion includes necessary and sufficient conditions for asymptotic independence, results on the asymptotic independence of statistics of interest, estimation

Identifying groups of variables with the potential of being large simultaneously

open access: yes, 2018
Identifying groups of variables that may be large simultaneously amounts to finding out which joint tail dependence coefficients of a multivariate distribution are positive.
