Incorporation of frailties into a non-proportional hazard regression model and its diagnostics for reliability modeling of downhole safety valves
Francisco Louzada, José A. Cuminato, Oscar M. H. Rodriguez +13
In this paper, our proposal consists of incorporating frailty into a statistical methodology for modeling time-to-event data, based on non-proportional hazards regression model. Sp…
Multiple repairable systems under dependent competing risks with nonparametric Frailty
Marco Pollo Almeida, Rafael Paixao, Pedro Ramos +3
The aim of this article is to analyze data from multiple repairable systems under the presence of dependent competing risks. In order to model this dependence structure, we adopted…
Objective Bayesian Inference for Repairable System Subject to Competing Risks
Marco Pollo, Vera Tomazella, Gustavo Gilardoni +3
Competing risks models for a repairable system subject to several failure modes are discussed. Under minimal repair, it is assumed that each failure mode has a power law intensity.…
Modeling cure fraction with frailty term in latent risk: a Bayesian approach
Agatha Sacramento Rodrigues, Vinicius Fernando Calsavara, Vera Lúcia Damasceno Tomazella
In this paper, we propose a flexible cure rate model with frailty term in latent risk, which is obtained by incorporating a frailty term in risk function of latent competing causes…
