On modelling insurance data by using a generalized lognormal distribution [PDF]

open access: yes, 2014
In this paper, a new heavy-tailed distribution is used to model data with a strong right tail, as often occurs in practical situations. The distribution proposed is derived from the lognormal distribution, by using the Marshall and Olkin procedure.

Dependent defaults and losses with factor copula models

open access: yesDependence Modeling, 2017
We present a class of flexible and tractable static factor models for the term structure of joint default probabilities, the factor copula models. These high-dimensional models remain parsimonious with paircopula constructions, and nest many standard ...

Multivariate measures of positive dependence [PDF]

open access: yes
In this paper a set of desirable properties for measures of positive dependence of ordered n-tuples of continuous random variables (n >= 2) is proposed and a class of multivariate positive dependence measures is introduced. We consider the comonotonicity

Dependence measure for length-biased survival data using copulas

open access: yesDependence Modeling, 2019
The linear correlation coefficient of Bravais-Pearson is considered a powerful indicator when the dependency relationship is linear and the error variate is normally distributed.
