The use of copula analysis to estimate the lifetime of bonds is gaining popularity in the financial sector. Taking this concept a step further, the following research project explores the use of the copula method in estimating the joint occurrence of bond default as a method of predictive analysis of bond lifetime. This is accomplished by means of an indepth discussion on copulas followed by a ...

We use a semiparametric GARCH-in-Mean copula model to examine the price evolution and volatility dynamics of crude oil, natural gas, hydrocarbon gas liquids markets using data from January 2002 December 2021. find that uncertainty has positive statistically significant effect on returns oil but negative ethane returns. also Frank is best describe (bivariate) dependence structures between market...

This paper deals with the impact of structure of dependency and the choice of procedures for rareevent simulation on the pricing of multi-name credit derivatives such as n to default swap and Collateralized Debt Obligations (CDO). The correlation between names defaulting has an effect on the value of the basket credit derivatives. We present a copula based simulation procedure for pricing baske...

background: in survival studies when the event times are dependent, performing of the analysis by using of methods based on independent assumption, leads to biased. in this paper, using copula function and considering the dependence structure between the event times, a parametric joint distribution has made fitting to the events, and the effective factors on each of these events would be determ...

This work considers stochastic comparisons of lifetimes series and parallel systems with dependent heterogeneous components having following the proportional odds (PO) model. The joint distribution component is modeled by Archimedean survival copula. We discuss some potential applications our findings in system reliability actuarial science.

In the literature of life-testing, general progressive censoring has been studied extensively. But, all the results have been developed under the key assumption that the units undertest are independently distributed. In this paper, we study general progressively Type-II censored order statistics arising from identical units under test which are jointly distributed according to an Archimedean co...

This research work investigates the theoretical foundations and computational aspects of constructing optimal bespoke CDO structures. Due to the evolutionary nature of the CDO design process, stochastic search methods that mimic the metaphor of natural biological evolution are applied. For efficient searching the optimal solution, the nondominating sort genetic algorithm NSGA-II is used, which ...
