Table 2.

Comparison of model performance on test set data via the IDI. A positive IDI with P < 0.05 indicates the new model achieves a statistically significant improvement in classification performance versus the old model. Models are listed in column 1, results from the schizophrenia group are reported in columns 2–3, and results from the AFib group are reported in columns 4–5.
