Abstract: Abstract Frailty and resilience models provide a convenient tool to introduce random effects, dependence and unobserved heterogeneity into the models for survival data. In this paper, we study the ageing of baseline distribution function $$H_0$$H0 relative to ageing of frailty distribution corresponding to $$H_0$$H0. We also study the relative ageing of frailty models having the same baseline distribution but different frailty distributions. Similar study is carried out for resilience models.
