Consideramos un modelo de supervivencia bivariante basado en la presencia de una covariable aleatoria no observada, frailty, que induce dependencia entre los tiempos de fallo y actúa bajo hipótesis de riesgo proporcional. Consideramos una distribución gamma para el frailty y distribuciones marginales Weibull e introducimos covariables explicativas, que actúan bajo hipótesis de vida acelerada. Introducimos además covariables en el parámetro de asociación.
We consider a bivariate survival model with the presence of an unobserved random covariate, frailty, that induces dependency between the failure times and acts according to a proportional hazard model. We consider gamma distribution for this frailty and Weibull marginal distributions and we introduce explanatory covariates that act according to an accelerated life model. We consider covariates in association parameter.
