Notes
depression_label should be interpreted as a dataset label, not a clinical diagnosis.- Numeric score columns should be interpreted as score-like variables, not precise clinical measurements.
- Because the label distribution is highly imbalanced, comparisons involving label
1 should be treated carefully.
