Input Data Specification Format: CSV or Excel (.xlsx). Organization: One file per metric. Filename: The filename (excluding extension) must strictly match the corresponding entry in metric_names (e.g., Accuracy.csv for metric Accuracy). Dimensions: Rows = Observations (n, e.g., Subjects), Columns = Datasets (N, e.g., Methods). Consistency: All files must have identical dimensions. Uneven sample sizes (missing data) are handled by automatic NaN padding (empty cells) to ensure a uniform matrix size, and pairwise deletion is applied during analysis.
