TABLE 2.

Estimation test results and diagnostic scores for Case 1, Case 2, and Case 3. The estimation performance metric includes correlation coefficients and mean absolute percentage error (MAPE). The diagnostic performance metric includes accuracy, precision, specificity, sensitivity, and F1 score. Here, TP and FN denote true positive and false negative, respectively, where positive and negative denote abnormal and normal, respectively. All indicators are rounded to the third decimal place.
