Table 1 Possible relations between transitions 1 → 3 and 2 → 3 if approach J is used

J.I

λ ₂₃(t,d)=λ ₁₃(t)

The hazard rate remains the same

J.II

λ ₂₃(t,d)=c·λ ₁₃(t)

The hazard rate changes by

the factor c (constant)

J.III.1

λ ₂₃(t,d)=c(d)·λ ₁₃(t)

c depends on d, the

time of ILRR

J.III.2

λ ₂₃(t,d)=c(t - d)·λ ₁₃(t)

c depends on t - d, the

time since ILRR

J.IV

λ ₂₃(t,d)=c(d,t - d)·λ ₁₃(t)

c depends on d as well as

on t - d the time since ILRR
