Coefficient paths for CoxBoost. Estimated parameters plotted against the norm of the parameter vector for CoxPath (top left), gradient boosting (top right), componentwise CoxBoost (bottom left), and CoxBoost with a mandatory covariate (bottom right). CoxPath steps and boosting steps selected by cross-validation are indicated by vertical lines. Covariates selected by all approaches up to this number of steps are indicated by solid curves, the others by dashed curves. For them and other strong covariates the UNIQID is given.
