Test results by year. The boxplots depict the test results on the test folds, stratified by year, across nine evaluation metrics: area under the receiver operating characteristic curve (\(\hbox {AUC}_{\textrm{ROC}}\)), area under the precision-recall-gain curve (\(\hbox {AUC}_{\textrm{PRG}}\)), percent correctly classified (PCC), true skill statistic (TSS), continuous Boyce index (CBI), Pearson correlation (COR), mean absolute error (MAE), root mean square error (RMSE), and mean log loss (logloss). The x-axis represents the year, while the y-axis indicates the metric
