We consider a pair of exchangeable lifetimes X; Y and the families of the conditional survival functions F_t(x;y) of (X-t; Y-t) given (X > t; Y > t). We analyze some properties of dependence and of ageing for F_t(x;y) and some relations among them.

Abstract
We consider a pair of exchangeable lifetimes X; Y and the families of the conditional survival functions F_t(x;y) of (X-t; Y-t) given (X > t; Y > t). We analyze some properties of dependence and of ageing for F_t(x;y) and some relations among them.File in questo prodotto:
