Notes:

This table reports bootstrap results of estimated SHAP in logistic regression. We run 1,000 times to compute the mean, standard deviation (s.d.), and 95% confidence interval (CI) for training (Panel A) and test data (Panel B). Panel C shows t- and p-values of t-test for comparison for the means between training and test data; the null hypothesis is that both means are equal to each other
