Statistical Analysis on Time to Blindness of Glaucoma Patients at Jimma University Specialized Hospital: Application of Accelerated Failure Time Model [PDF]
Journal of Ophthalmology, 2022 Background. Glaucoma is one of the most frequent vision-threatening eye diseases. It is frequently associated with excessive intraocular pressure (IOP), which can cause vision loss and damaged optic nerves.

Flexible boosting of accelerated failure time models [PDF]
BMC Bioinformatics, 2008 Background When boosting algorithms are used for building survival models from high-dimensional data, it is common to fit a Cox proportional hazards model or to use least squares techniques for fitting semiparametric accelerated failure time models ...

Weighted estimation of the accelerated failure time model in the presence of dependent censoring. [PDF]
PLoS ONE, 2015 Independent censoring is a crucial assumption in survival analysis. However, this is impractical in many medical studies, where the presence of dependent censoring leads to difficulty in analyzing covariate effects on disease outcomes.

An empirical analysis of post-work grocery shopping activity duration using modified accelerated failure time model to differentiate time-dependent and time-independent covariates. [PDF]
PLoS ONE, 2018 In this paper, the accelerated failure time (AFT) model is modified to analyze post-work grocery shopping activity duration. Much previous shopping duration analysis was conducted using the proportional hazard (PH) modeling approach.

Semiparametric accelerated failure time model estimation with time-varying covariates
, 2023 The semiparametric accelerated failure time model is a potential alternative to the popular Cox proportional hazards model, especially when the proportional hazards assumption is violated.
