Análise de referência Bayesiana para o modelo Weibull na aplicação de riscos competitivos
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Estatística - PPGEs, 2009-01-30)
There are situations where various risk factors of failure are present, in the same time, in the life of system. For this reason we say that these factors are competing to cause the system failure. However, only one of ...
Análise de confiabilidade de sistemas de máquinas colhedoras de cana-de-açúcar usando o modelo q-Weibull
(Universidade Federal da BahiaEscola PolitécnicaPrograma de Pós-graduação em Engenharia IndustrialUFBAbrasil, 2019-09-11)
A colheita de cana-de-açúcar com o uso de máquinas colhedoras influencia diretamente o fornecimento de matéria-prima requerido pelas indústrias para a produção de açúcar, etanol biocombustível e bioenergia. O estudo de ...
The log-Weibull-negative-binomial regression model under latent failure causes and presence of randomized activation schemes
(Taylor and FrancisPhiladelphia, 2015-08)
The purpose of this paper is to develop a Bayesian approach for the log-Weibull-negative-binomial regression
model under latent failure causes and presence of a randomized activation mechanism. We assume
the number of ...
Estimating the number of ozone peaks in Mexico City using a non-homogeneous Poisson model
(JOHN WILEY & SONS LTDLONDON, 2008)
In this paper, we consider the problem of estimating the number of times an air quality standard is exceeded in a given period of time. A non-homogeneous Poisson model is proposed to analyse this issue. The rate at which ...
The exponentiated generalized gamma distribution with application to lifetime data
(TAYLOR & FRANCIS LTD, 2011)
A four-parameter extension of the generalized gamma distribution capable of modelling a bathtub-shaped hazard rate function is defined and studied. The beauty and importance of this distribution lies in its ability to model ...
Weibull and generalised exponential overdispersion models with an application to ozone air pollution
(TAYLOR & FRANCIS LTDABINGDON, 2012)
We consider the problem of estimating the mean and variance of the time between occurrences of an event of interest (inter-occurrences times) where some forms of dependence between two consecutive time intervals are allowed. ...
A generalized modified Weibull distribution for lifetime modeling
(ELSEVIER SCIENCE BV, 2008)
A four parameter generalization of the Weibull distribution capable of modeling a bathtub-shaped hazard rate function is defined and studied. The beauty and importance of this distribution lies in its ability to model ...
Análise clássica e bayesiana do modelo Weibull modificado generalizado
(Universidade Estadual Paulista (UNESP), 2014)
Testes em modelos weibull na forma estendida de Marshall-Olkin
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Matemática Aplicada e EstatísticaProbabilidade e Estatística; Modelagem Matemática, 2011-12-28)
In survival analysis, the response is usually the time until the occurrence of an event of interest,
called failure time. The main characteristic of survival data is the presence of censoring which
is a partial observation ...
