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 ...
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, ...
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 ...
Heteroscedastic Log-exponentiated Weibull Regression Model
(Taylor and Francis Ltd., 2017)
Modelo Weibull modificado de longa duração
(Universidade Federal de São CarlosUFSCarPrograma de Pós-graduação em EstatísticaCâmpus São Carlos, 2011-12-07)
When a group of patients is monitored until a pre-established date for observation of the recurrence time of an event, it is possible that, at the end of the monitoring period, a parcel of such group has not yet suffered ...
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 ...
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 ...
A Log-Linear Regression Model for the Beta-Weibull Distribution
(TAYLOR & FRANCIS INC, 2011)
We introduce the log-beta Weibull regression model based on the beta Weibull distribution (Famoye et al., 2005; Lee et al., 2007). We derive expansions for the moment generating function which do not depend on complicated ...
