Figure 5From: Flexible boosting of accelerated failure time modelsBoxplots of the predictive Weibull log likelihood estimates. Boxplots of the predictive Weibull log likelihood estimates, as obtained from the 50 Weibull-distributed test samples following Model (10). The predictive log likelihood values of the null model were obtained via maximum likelihood estimation with no covariates and an intercept only. Similar results were obtained for the log-logistic and lognormal models.Back to article page
