Figure 7From: Flexible boosting of accelerated failure time modelsAnalysis of the Barrier stage II colon cancer data – prediction error curves for parametric and semiparametric AFT models. Prediction error curves obtained from boosting with the negative log-logistic log likelihood, L2Boosting for semiparametric AFT models, and L1 penalized estimation for semiparametric AFT models (Lasso).Back to article page
