A multiple time scale survival model with a cure fraction
(SPRINGERNEW YORK, 2012)
Many recent survival studies propose modeling data with a cure fraction, i.e., data in which part of the population is not susceptible to the event of interest. This event may occur more than once for the same individual ...
A general hazard model for lifetime data in the presence of cure rate
(ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD, 2011)
Historically, the cure rate model has been used for modeling time-to-event data within which a significant proportion of patients are assumed to be cured of illnesses, including breast cancer, non-Hodgkin lymphoma, leukemia, ...
On the unification of long-term survival models
(ELSEVIER SCIENCE BV, 2009)
In this paper we extend the long-term survival model proposed by Chen et al. [Chen, M.-H., Ibrahim, J.G., Sinha, D., 1999. A new Bayesian model for survival data with a surviving fraction. journal of the American Statistical ...
Modelo de mistura paramétrico com fragilidade na presença de covariáveis
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Estatística - PPGEs, 2013-04-23)
Some studies involving survival data are characterized by showing a significant proportion of censored data, that is, individuals who will never experience the event of interest, even if accompanied by a long period of ...
Modelo de mistura padrão com tempo de falha exponencial e censura informativa
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Estatística - PPGEs, 2010-06-25)
In this work we consider the long-term survival model introduced by Berkson & Gage (1952), for modeling survival data of nonhomogeneous populations, where a subpopulation does not present the event of interest, despite a ...
Modelos de sobrevivência com fração de cura usando um termo de fragilidade e tempo de vida Weibull modificada generalizada
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Estatística - PPGEs, 2011-02-24)
In survival analysis, some studies are characterized by having a significant fraction of units that will never suffer the event of interest, even if accompanied by a long period of time. For the analysis of long-term data, ...
Modelo de mistura padrão com tempos de vida exponenciais ponderados
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Estatística - PPGEs, 2010-03-05)
In this work, we brie_y introduce the concepts of long-term survival analysis. We dedicated ourselves exclusively to the standard mixture cure model from Boag (1949) and Berkson & Gage (1952), showing its deduction and ...
Models for inflated data applied to credit risk analysis
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Estatística - PPGEsCâmpus São Carlos, 2016-09-27)
In this thesis, we introduce a methodology based on zero-inflated survival data for the
purposes of dealing with propensity to default (credit risk) in bank loan portfolios. Our
approach enables us to accommodate three ...
