Abstract

In the present work we first discuss the structure and properties of the ageing function of the Gumbel–Barnett copula in the exchangeable case. Then we define and illustrate the ageing notions such as IFR, DMRL, NBU etc for copulas using the weak copula ageing property of the Gumbel–Barnett copula.
