Boxplots of the Weibull parameter estimates when 5 informative covariates are present. Boxplots of the estimates of β = (0.5, 0.25, -0.25, -0.5, 0.5)^⊤, as obtained from the 50 Weibull-distributed samples following Model (10). Grey boxplots correspond to boosting estimates, white boxplots correspond to maximum likelihood estimates. Similar results were obtained for the log-logistic and lognormal models.
