Using Quantile Regression for Duration Analysis [PDF]

Quantile regression methods are emerging as a popular technique in econometrics and biometrics for exploring the distribution of duration data. This paper discusses quantile regression for duration analysis allowing for a flexible specification of the ...

Mathematical Modeling of Degradation Data Using a Proportional Hazard Gumbel Type-II Distribution Under Generalized Progressive Hybrid Censoring

Mathematics
Mathematical modeling of degradation data is essential for quantifying the lifetime, reliability, and long-term stability of advanced materials when a direct experimental assessment is costly or limited.

SURVIVAL ANALYSIS AND LENGTH-BIASED SAMPLING

Croatian Operational Research Review, 2010
When survival data are colleted as part of a prevalent cohort study, the recruited cases have already experienced their initiating event. These prevalent cases are then followed for a fixed period of time at the end of which the subjects will either have

Computational Methods in Survival Analysis [PDF]

Survival analysis is widely used in the fields of medical science, pharmaceutics, reliability and financial engineering, and many others to analyze positive random phenomena defined by event occurrences of particular interest.

Frailty in survival analysis models (parametric frailty, parametric shared frailty, and frailty in Cox models [PDF]

Frailty models are used to model survival times in the presence of overdispersion or group-specific random effects. The latter are distinguished from the former by the term "shared" frailty models.

Semiparametric Estimation of Single-Index Transition Intensities [PDF]

This research develops semiparametric kernel-based estimators of state-specific conditional transition intensitiesm, hs (y|x), for duration models with right-censoring and/or multiple destinations (competing risks).

Instrumental variable estimation for duration data [PDF]

In this article we focus on time-to-event studies with arandomised treatment assignment that may be compromised byselective compliance. Contrary to most of the extensive literatureon evaluation studies we do not consider the effect of thetreatment on ...
