ACCELERATED FAILURE TIME MODELS WITH NONLINEAR COVARIATES EFFECTS

Australian & New Zealand Journal of Statistics, 2007
SummaryAs a flexible alternative to the Cox model, the accelerated failure time (AFT) model assumes that the event time of interest depends on the covariates through a regression function. The AFT model with non‐parametric covariate effects is investigated, when variable selection is desired along with estimation.

Accelerated Failure Time Models For Load Sharing Systems

IEEE Transactions on Reliability, 2014
We model the load sharing phenomenon in a k-out-of- m system through the accelerated failure time model. This model leads to multivariate families of distributions for ordered random variables, which are particular cases of the sequential order statistics.

The Accelerated Failure Time Model Under Biased Sampling

Biometrics, 2010
Summary Chen (2009, Biometrics) studies the semi‐parametric accelerated failure time model for data that are size biased. Chen considers only the uncensored case and uses hazard‐based estimation methods originally developed for censored observations. However, for uncensored data, a simple linear regression on the log scale is more natural and provides

Bayesian semiparametric inference for the accelerated failure‐time model

Canadian Journal of Statistics, 1997
AbstractBayesian semiparametric inference is considered for a loglinear model. This model consists of a parametric component for the regression coefficients and a nonparametric component for the unknown error distribution. Bayesian analysis is studied for the case of a parametric prior on the regression coefficients and a mixture‐of‐Dirichlet‐processes

Analysis of Failure Time Data with Mixed-Effects Accelerated Failure Time Model

Communications in Statistics - Simulation and Computation, 2011
In randomized clinical trials or observational studies, subjects are recruited at multiple treating sites. Factors that vary across sites may have some influence on outcomes; therefore, they need to be taken into account to get better results. We apply the accelerated failure time (AFT) model with linear mixed effects to analyze failure time data ...

Linear Interpolation With a Nonparametric Accelerated Failure-Time Model

Journal of the American Statistical Association, 1988
Abstract Assuming a nonparametric accelerated failure-time model, a method is proposed for extrapolating low stress-response probabilities on negative-sloping line segments in the stress-failure-time plane. The method (analogous to linear interpolation in dose-response studies) results in simultaneous extrapolation ahead in time and down in stress.
