Table 6.
Feature correlation values. We summarize the Pearson correlation coefficients and Spearman rank correlation coefficients between the calculated Shapley additive explanations (SHAP) values and the respective features. For each feature, we also present the coefficients of the logistic regression model and their respective odds ratios.
