Module stats 

Statistical analysis and Pareto front calculation.

This module provides tools for analyzing codec comparison results, including Pareto front calculation for rate-distortion analysis.

Core Statistics

• Summary: Descriptive statistics (mean, median, std_dev, percentiles)
• median, mean, std_dev: Basic statistical functions
• percentile, percentile_u32: Percentile calculation (R-7 interpolation)
• trimmed_mean: Robust mean excluding outliers
• iqr: Interquartile range

Rate-Distortion Analysis

• bd_rate: Bjontegaard Delta Rate calculation
• ParetoFront: Pareto-optimal points on RD curve
