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

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.
