gnn-statistical-analysis

name	gnn-statistical-analysis
description	GNN advanced statistical analysis and result aggregation. Use when performing statistical analysis on simulation results, cross-simulation aggregation, computing information-theoretic metrics, or creating analytical visualizations of pipeline outputs.

GNN Statistical Analysis (Step 16)

Purpose

Performs advanced statistical analysis on pipeline outputs including simulation results, cross-framework comparison, Active Inference metrics, and comprehensive statistical reporting.

Key Commands

# Run analysis
python src/16_analysis.py --target-dir input/gnn_files --output-dir output --verbose

# As part of pipeline
python src/main.py --only-steps 16 --verbose
