A matrix approach to the statistics of longevity in heterogeneous frailty models
frailty heterogeneity individual stochasticity longevity Markov chains mortality
2014/11/27
Background: The gamma-Gompertz model is a fixed frailty model in which baseline mortality increases exponentially with age, frailty has a proportional effect on mortality, and frailty at birth follows...

2014/11/26
Background: In survival analysis a large literature using frailty models, or models with unobserved heterogeneity, exists. In the growing literature and modelling on multistate models, this issue is o...
