Abstract:

In this paper, we compare three methods to distinguish between Cox's proportional hazards model and Aalen's additive hazards model in censored survival data. The statistics are based on distances between estimated survival curve and Kaplan-Meier survival curve, chi-squared goodness-of-fit test, and R2-type measures of explained residual variation, under each model. A Monte Carlo study was carried out to compare the performance of these models and the behavior of Cox's model and Aalen's model in the presence of model misspecification and an independent censoring mechanism.
