Un frailty aditivo en modelos de supervivencia bivariante

Bivariate survival models based on the presence of an unobseved random covariate, grailty, tend to assume a proportional hazard hypothesis. A bivariate survival model is constructed. It is based on frailty model that acts additivelky on the hazard function.Keywords: survival times, frailty, dependen...

Sumario: Bivariate survival models based on the presence of an unobseved random covariate, grailty, tend to assume a proportional hazard hypothesis. A bivariate survival model is constructed. It is based on frailty model that acts additivelky on the hazard function.Keywords: survival times, frailty, dependence, proportional risk.
