The upper curve is the ROC curve (AUC) with recall (sensitivity) vs false positive rate. The lower curve is the precision-recall curve AUCpr with precision vs recall for the a upper 15 % class of grain yield in environment 6 (GY-6) of classifiers MLP (green) and PNN (blue); b upper 30 % class of grain yield in environment 6 (GY-6) of MLP (green) and PNN (blue); c lower 15 % class of days to heading in environment 3 (DTH-3) of MLP (green) and PNN (blue); d lower 30 % class of days to heading in environment 3 (DTH-3) of MLP (green) and PNN (blue)
