The complementary exponential power lifetime model
(Elsevier B.V., 2011-03-01)
In this paper we propose a new lifetime distribution which can handle bathtub-shaped unimodal increasing and decreasing hazard rate functions The model has three parameters and generalizes the exponential power distribution ...
Robust Differentiable Functionals in the Additive Hazards Model
(Scientific Research Publishing, 2015-10)
In this article we present a new family of estimators for the regression parameter β in the Additive Hazards Model which represents a gain in robustness not only against outliers but also against unspecific contamination ...

Different Approaches for Modeling Grouped Survival Data: A Mango Tree Study
(AMER STATISTICAL ASSOC & INT BIOMETRIC SOC, 2009)
Interval-censored survival data, in which the event of interest is not observed exactly but is only known to occur within some time interval, occur very frequently. In some situations, event times might be censored into ...
Choosing between Cox proportional hazards and logistic models for interval-censored data via bootstrap
(Carfax Publishing, 2003-01-01)
This work develops a new methodology in order to discriminate models for interval-censored data based on bootstrap residual simulation by observing the deviance difference from one model in relation to another, according ...
Estimation of the mean quality-adjusted survival using a multistate model for the sojourn times
(ELSEVIER SCIENCE BV, 2008)
In clinical trials, it may be of interest taking into account physical and emotional well-being in addition to survival when comparing treatments. Quality-adjusted survival time has the advantage of incorporating information ...
A multi criteria analog model for assessing the vulnerability of rural catchments to road spills of hazardous substances
(Elsevier B.V., 2017-05-01)
Road spills of hazardous substances are common in developing countries due to increasing industrialization and traffic accidents, and represent a serious threat to soils and water in catchments. There is abundant literature ...
