Abstract:RESUMENLos modelos de supervivencia bivariante dasados en la presencia de una covariable aleatoria no observada, frailty, suelen asumir hipótesis de riesgo proporcional. Construimos un nuevo modelo de supervivencia bivariante basado en la presencia de un frailty que actúa aditivamente en la función de riesgo.ABSTRACT Bivariante survical models based on the presence of an unobserved random covariante, frailty, tend to assume proportional hazard hypothesis. A bivariante survival model is constructed. It is based… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
