On preservation of ageing under minimum for dependent random lifetimes
In this note we consider a vector (X1, X2) of lifetimes whose dependence
is described by an Archimedean copula, and we provide conditions useful to describe the relationships between ageing properties of X1 and X2
and ageing properties of their minimum. Examples are also provided.
