The polysurvival model with long-term survivors
(Brazilian Statistical AssociationSão Paulo, 2012)
Long-term survival models have historically been considered for analyzing time-to-event data with long-term survivors fraction. However, situations in which a fraction (1 - p) of systems is subject to failure from independent ...
A hands-on approach for fitting long-term survival models under the GAMLSS framework
(ELSEVIER IRELAND LTD, 2010)
In many data sets from clinical studies there are patients insusceptible to the occurrence of the event of interest. Survival models which ignore this fact are generally inadequate. The main goal of this paper is to describe ...
Survival model induced by discrete frailty for modeling of lifetime data with long-term survivors and change-point
(Taylor & Francis Inc, 2019-07-30)
Frailty models are used for modeling heterogeneity in the data analysis of lifetimes. Analysis that ignore frailty when it is present leads to incorrect inferences. In survival analysis, the distribution of frailty is ...
A general long-term aging model with different underlying activation mechanisms: Modeling, Bayesian estimation, and case influence diagnostics
(Taylor & Francis Inc, 2017-01-01)
In this paper we propose a general cure rate aging model. Our approach enables different underlying activation mechanisms which lead to the event of interest. The number of competing causes of the event of interest is ...
A nonlinear model for the long-term hydro-thermal generation scheduling problem over multiple areas with transmission constraints
(Ieee, 2009-01-01)
This paper presents a nonlinear model with individual representation of plants for the centralized long-term hydrothermal scheduling problem over multiple areas. In addition to common aspects of long-term scheduling, this ...
A Bayesian Long-term Survival Model Parametrized in the Cured Fraction
(WILEY-V C H VERLAG GMBH, 2009)
The main goal of this paper is to investigate a cure rate model that comprehends some well-known proposals found in the literature. In our work the number of competing causes of the event of interest follows the negative ...
