CoxRidge-package: Fit penalized Cox models with fixed and time varying effects of the covariates.


Fits penalized Cox models using ridge penalties and a REML-type algorithm for optimization. The methods can be applied also to non-proportional hazards models where some or all of the covariates can be modelled with time varying effects.
