pssm-package: Joint proportional hazards model for survival and progression...

In pssm: Piecewise Exponential Model for Time to Progression and Time from Progression to Death

Description

Fits a joint model for interval censored time to progression and subsequent survival. Progression is assumed to always occure before death. The underlying hazard function is assumed to be piecewise constant.

The function pssm fits the model and outputs a pssm-object S4 object, this can input to pssm.survivalcurv which outputs a function of time, that can be used to create time to progression and survival curves for the model with specified covariate values.

In addition pssm.simulate is given to generate data to test the model. Functions "llikef","rprog","sprog" are helper functions, methods "plot","print" and "summary" are available.
