Abstract: Abstract. Accelerated failure time (AFT) models serve as a useful tool for survival analysis to investigate the relationship between the time of an occurrence and the associated covariates, subject to right censoring. Under the high-dimensional… read more here.

Abstract: Accelerated Failure Time (AFT) models are viable alternatives to the Cox proportional hazard model, where failure times are explicitly modelled with respect to covariates. A major problem with parametric AFT models in practice is that… read more here.
