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
(SPRINGER, 2010)
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 - 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, ...
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 ...

Modelo estadístico para el análisis de variables negativas con aplicación a pruebas de contracción en concreto
(Fondo Editorial EIA - Universidad EIA, 2022-06-01)
En algunas áreas de conocimiento se pueden presentar fenómenos que son representados por variables aleatorias negativas (ℝ-) ; contar con un modelo estadístico es crucial para representar esos fenómenos y explicarlos en ...
General results for the Kumaraswamy-G distribution
(TAYLOR & FRANCIS LTDABINGDON, 2012)
For any continuous baseline G distribution [G. M. Cordeiro and M. de Castro, A new family of generalized distributions, J. Statist. Comput. Simul. 81 (2011), pp. 883-898], proposed a new generalized distribution (denoted ...
Generalized log-gamma regression models with cure fraction
(SPRINGER, 2009)
In this paper, the generalized log-gamma regression model is modified to allow the possibility that long-term survivors may be present in the data. This modification leads to a generalized log-gamma regression model with ...
Modelación de derivados europeos con distribuciones no gaussianas
(2014)
El modelo Black-Scholes (1973) para valoración de opciones europeas es ampliamente usado en el mercado debido a su fácil implementación. Sin embargo, hay evidencia empírica que contradice los supuestos básicos del modelo ...
