Piecewise-linear criterion functions in oblique survival tree induction

作者:

Highlights:

• I proposed an oblique survival tree that is able to cope with right-censored data.

• The induction algorithm is based on the minimization of the CPL criterion functions.

• A split-complexity measure with a 10-fold cross-validation was used to prune a tree.

• The predictive ability of the method was evaluated using synthetic and real data.

• The outcomes were compared with two existing univariate tree models.

• The obtained survival trees are small and offer a good predictive ability.
