    metric is calculated globally by counting the total number of correctly
    predicted rows.
    
    
    Attributes:
        precision:
            Precision is the fraction of actual positive predictions that
            had positive actual labels. For multiclass this is a macro-
            averaged metric treating each class as a binary classifier.
        recall:
            Recall is the fraction of actual positive labels that were
            given a positive prediction. For multiclass this is a macro-
            averaged metric.
        accuracy:
            Accuracy is the fraction of predictions given the correct
            label. For multiclass this is a micro-averaged metric.
        threshold:
            Threshold at which the metrics are computed. For binary
            classification models this is the positive class threshold.
            For multi-class classfication models this is the confidence
            threshold.
        f1_score:
            The F1 score is an average of recall and precision. For
            multiclass this is a macro-averaged metric.
        log_loss:
            Logarithmic Loss. For multiclass this is a macro-averaged
            metric.
        roc_auc:
            Area Under a ROC Curve. For multiclass this is a macro-
            averaged metric.
