ABSTRACT
Set t0 = 0. If the GS model holds on Em then the survival function Sx(·)(t) verifies the
equality:
Sx(·)(t) = Sxi(t− ti−1 + t∗i−1), if t ∈ [ti−1, ti) (i = 1, 2, . . . ,m), (12.2) where t∗i can be found by solving the equations
Sx1(t1) = Sx2(t ∗ 1), . . . , Sxi(ti − ti−1 + t∗i−1) = Sxi+1(t∗i ) (i = 1, . . . ,m− 1).
