G-estimation for Accelerated Failure Time Models
There is an increasing interest in life-course epidemiology (Ben-Shlomo 2007; Ben-Shlomo and Kuh 2002), with the quantification of the effects of exposures over long periods of time. For example, several papers recently have examined the effects of socioeconomic position at different stages of life, and changes in that exposure between these stages, on outcomes including risk of stroke and resp...
متن کاملSurvival analysis of thalassemia major patients using Cox, Gompertz proportional hazard and Weibull accelerated failure time models
Background: Thalassemia major (TM) is a severe disease and the most common anemia worldwide. The survival time of the disease and its risk factors are of importance for physicians. The present study was conducted to apply the semi-parametric Cox PH model and use parametric proportional hazards (PH) and accelerated failure time (AFT) models to identify the risk factors related to survival of TM ...
متن کاملComparison of Proportional Hazards and Accelerated Failure Time Models
The eld of survival analysis has experienced tremendous growth during the latter half of the 20th century. The methodological developments of survival analysis that have had the most profound impact are the Kaplan-Meier method for estimating the survival function, the log-rank test for comparing the equality of two or more survival distributions, and the Cox proportional hazards (PH) model for...
متن کاملParametric proportional hazards and accelerated failure time models
A unified implementation of parametric proportional hazards (PH) and accelerated failure time (AFT) models for right-censored or intervalcensored and left-truncated data is described. The description here is válid for time-constant covariates, but the necessary modifications for handling time-varying covariates are implemented in eha. Note that only piecewise constant time variation is handled.
متن کاملRegression calibration in semiparametric accelerated failure time models.
In large cohort studies, it often happens that some covariates are expensive to measure and hence only measured on a validation set. On the other hand, relatively cheap but error-prone measurements of the covariates are available for all subjects. Regression calibration (RC) estimation method (Prentice, 1982, Biometrika 69, 331-342) is a popular method for analyzing such data and has been appli...
