Fractions of unvaccinated individuals in the test set as a function of centile bins of predicted probabilities to not vaccinate from the full XGBoost model. The 99th centile bin comprises 6,385 individuals that have only an 18.8% (95% CI, 17.919.8%) chance of vaccinating. The error bars indicate 95% CIs computed using bootstrapping. The black dashed line indicates the average fraction of unvaccinated individuals in the study population.
