casebase: A Statistical Software Tool for Survival Analysis¶
This approach allows the explicit inclusion of the time variable into the model, which enables the user to fit a wide class of parametric hazard functions. For example, including time linearly recovers the Gompertz hazard, whereas including time logarithmically recovers the Weibull hazard; not including time at all corresponds to the exponential hazard.
The theoretical properties of this approach have been studied in Saarela & Arjas (2015) and Saarela (2015).
The software is still in development mode.
