Power laws in the Roman Empire: a survival analysis
Pedro L. Ramos, Luciano da F. Costa, Francisco Louzada +1
The Roman Empire shaped Western civilization, and many Roman principles are embodied in modern institutions. Although its political institutions proved both resilient and adaptable…
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…
An Extended Poisson Family of Life Distribution: A Unified Approach in Competitive and Complementary Risks
Pedro L. Ramos, Dipak K. Dey, Francisco Louzada +1
In this paper, we introduce a new approach to generate flexible parametric families of distributions. These models arise on competitive and complementary risks scenario, in which t…
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.…
The Frechet distribution: Estimation and Application an Overview
Pedro Luiz Ramos, Francisco Louzada, Eduardo Ramos +1
In this article, we consider the problem of estimating the parameters of the Fréchet distribution from both frequentist and Bayesian points of view. First we briefly describe diffe…
