Generalized log-gamma regression models with cure fraction
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 ...
Residuals for log-Burr XII regression models in survival analysis
(ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD, 2011)
In this paper, we compare three residuals to assess departures from the error assumptions as well as to detect outlying observations in log-Burr XII regression models with censored observations. These residuals can also ...
Deviance residuals in generalised log-gamma regression models with censored observations
(TAYLOR & FRANCIS LTD, 2008)
In this article, we compare three residuals based on the deviance component in generalised log-gamma regression models with censored observations. For different parameter settings, sample sizes and censoring percentages, ...
The generalized log-gamma mixture model with covariates: local influence and residual analysis
(SPRINGER HEIDELBERG, 2009)
In a sample of censored survival times, the presence of an immune proportion of individuals who are not subject to death, failure or relapse, may be indicated by a relatively high number of individuals with large censored ...
Estimating the bioenergy potential of Pinus radiata plantations in Chile

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 ...
DETERMINATION OF THE E/G RATIO OF WOOD LOGS USING TRANSVERSE VIBRATION
(SLOVAK FOREST PRODUCTS RESEARCH INSTBRATISLAVA, 2012)
The Bernoulli's model for vibration of beams is often used to make predictions of bending modulus of elasticity when using dynamic tests. However this model ignores the rotary inertia and shear. Such effects can be added ...
Log-modified Weibull regression models with censored data: Sensitivity and residual analysis
(ELSEVIER SCIENCE BV, 2008)
This paper proposes a regression model considering the modified Weibull distribution. This distribution can be used to model bathtub-shaped failure rate functions. Assuming censored data, we consider maximum likelihood and ...
Influence diagnostics for polyhazard models in the presence of covariates
(SPRINGER HEIDELBERG, 2008)
In this paper, we present various diagnostic methods for polyhazard models. Polyhazard models are a flexible family for fitting lifetime data. Their main advantage over the single hazard models, such as the Weibull and the ...
