WebIn this model, the hazard rate is a multiplicative function of the baseline hazard and the hazard ratios can be interpreted the same way as in the semi-parametric proportional hazards model. Accelerated Failure Time (AFT) models are a class of parametric survival models that can be linearized by taking the natural log of the survival time model. WebHazard Ratio. Definition 1: The ratio of the observed number of failures (“deaths”) divided by the expected number of failures d/e (using the terminology from Log-Rank Test) is called the failure rate. For two survival distributions, the ratio of the failure rates is called the hazard ratio (aka the relative risk or risk ratio), i.e.
