General results for the beta-modified Weibull distribution
(TAYLOR & FRANCIS LTD, 2011)
We study in detail the so-called beta-modified Weibull distribution, motivated by the wide use of the Weibull distribution in practice, and also for the fact that the generalization provides a continuous crossover towards ...
The beta modified Weibull distribution
A five-parameter distribution so-called the beta modified Weibull distribution is defined and studied. The new distribution contains, as special submodels, several important distributions discussed in the literature, such ...
Joint statistics for two correlated Weibull variates

A compound class of Weibull and power series distributions
(ELSEVIER SCIENCE BV, 2011)
In this paper we introduce the Weibull power series (WPS) class of distributions which is obtained by compounding Weibull and power series distributions where the compounding procedure follows same way that was previously ...
The generalized inverse Weibull distribution
The inverse Weibull distribution has the ability to model failure rates which are quite common in reliability and biological studies. A three-parameter generalized inverse Weibull distribution with decreasing and unimodal ...
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, 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, ...
Extensões da Distribuição Weibull Aplicadas na Análise de Séries Climatológicas
(Universidade Estadual Paulista (UNESP), 2017-06-23)
Na análise de séries climatológicas, a metodologia conhecida como “análise de frequências” inicia-se, após a verificação da validade de algumas suposições, pela escolha e ajuste de uma distribuição de probabilidade. A etapa ...
A Note on the Prior Distributions of Weibull Parameters for the Reliability Function
(Taylor & Francis Inc, 2009-01-01)
In Bayesian Inference it is often desirable to have a posterior density reflecting mainly the information from sample data. To achieve this purpose it is important to employ prior densities which add little information to ...
On the weibull autocorrelation and power spectrum functions: Field trials and validation
(Ieee-inst Electrical Electronics Engineers IncPiscatawayEUA, 2006)
Extensões dos modelos de sobrevivência referente a distribuição Weibull
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-graduação em Estatística, 2014-03-07)
In this dissertation, two models of probability distributions for the lifetimes until the occurrence of the event produced by a specific cause for elements in a population are reviewed. The first revised model is called ...
