Transfer learning for accelerated failure time model with microarray data [PDF]

open access: yesBMC Bioinformatics
Background In microarray prognostic studies, researchers aim to identify genes associated with disease progression. However, due to the rarity of certain diseases and the cost of sample collection, researchers often face the challenge of limited sample ...

Accelerated failure-time model with weighted least-squares estimation: application on survival of HIV positives [PDF]

open access: yesArchives of Public Health, 2021
Background Survival analysis is the most appropriate method of analysis for time-to-event data. The classical accelerated failure-time model is a more powerful and interpretable model than the Cox proportional hazards model, provided that model imposed ...

Modeling the recovery time of patients with coronavirus disease 2019 using an accelerated failure time model [PDF]

open access: yesJournal of International Medical Research, 2021
Objective To identify factors associated with recovery time from coronavirus disease 2019 (COVID-19). Methods In this retrospective study, data for patients with COVID-19 were obtained between 21 June and 30 August 2020. An accelerated failure time (AFT)

Prediction Intervals for the Failure Time of Prestressed Concrete Beams [PDF]

open access: yesAdvances in Materials Science and Engineering, 2016
The aim is the prediction of the failure time of prestressed concrete beams under low cyclic load. Since the experiments last long for low load, accelerated failure tests with higher load are conducted.

UJI HIDUP DIPERCEPAT PADA DISTRIBUSI EKSPONENSIAL TERSENSOR TIPE II DENGAN TEGANGAN KONSTAN [PDF]

open access: yesMedia Statistika, 2010
Accelerated Life Testing (ALT) is used to obtain information quickly on life distribution, failure rates and reliabilities. ALT is achieved by subjecting the test units to conditions such that the failure occur sooner. Prediction of long term reliability

Parametric survival model to identify the predictors of breast cancer mortality: An accelerated failure time approach

open access: yesJournal of Research in Medical Sciences, 2020
Background: Breast cancer (BC) was the fifth cause of mortality worldwide in 2015 and second cause of mortality in Iran in 2012. This study aimed to explore factors associated with survival of patients with BC using parametric survival models.

Mediation Analysis for Censored Survival Data Under an Accelerated Failure Time Model. [PDF]

open access: yesEpidemiology, 2017
Recent advances in causal mediation analysis have formalized conditions for estimating direct and indirect effects in various contexts. These approaches have been extended to a number of models for survival outcomes including accelerated failure time ...

Generalized Accelerated Failure Time Models for Recurrent Events

open access: yesMathematics, 2022
For analyzing recurrent event data, we consider a generalization of the classical accelerated failure time model. In the proposed approach, the general function is no longer assumed to be a singleton but allowed to be time-varying.

Weighted Log-Rank Statistics for Accelerated Failure Time Model

open access: yesStats, 2021
This paper improves the sensitivity of the Gρ family of weighted log-rank tests for the accelerated failure time model, accommodating realistic alternatives in survival analysis with censored data, such as heavy censoring and crossing hazards.

Interval Mapping Using Nonparametric Accelerated Failure Time Cure Model [PDF]

open access: yesJournal of Statistical Theory and Applications (JSTA), 2013
Many important problems in evolutionary biology begin with observations of phenotypic variation. Suppose time to an event-data are used to map quantitative trait loci (QTL) and underlying population is a mixture of susceptible and non-susceptible ...
