Simulation Comparisons of Semi-Parametric Accelerated Failure Time Model With Different Bandwidths
<p>The proportional hazards (PH) model and the accelerated failure time (AFT) model are the most popular models to fit the censoring data. Sometimes, the PH assumption cannot be satisfied, and therefore, the AFT model becomes a useful alternative to the PH model. Comparing with the least square …

A study of the robustness of Cox's proportional hazards model used in testing for covariate effects
There are two important statistical models for multivariate survival analysis, proportional hazards(PH) models and accelerated failure time(AFT) model. PH analysis is most commonly used multivariate approach for analysing survival time data. For example, in clinical investigations where several …

Group Selection in Semiparametric and Nonparametric Accelerated Failure Time Models
In survival analysis, a number of regression models can be used to estimate the effects of covariates on the censored survival outcome. When covariates can be naturally grouped, group selection is important in these models. Motivated by the group bridge approach for variable selection in a multiple …
