Gradient boosting did no better than logistic regression on HPV vaccine hesitancy

In 1,156 Cameroonian parents of children aged 9 to 18, XGBoost, random forest and logistic regression predicted HPV vaccine hesitancy almost identically (AUC 0.841-0.870, XGBoost 0.870 against 0.869, p=0.965), with logistic regression the best calibrated.
