Expand description

Detect regression using statistical window + Bayesian Change Point Detection

This function combines three criteria for robust regression detection:

  1. Statistical significance (outside confidence interval)
  2. Practical significance (exceeds threshold percentage)
  3. Change point probability (likely distribution shift)

All three conditions must be met for a regression to be flagged.
