Correlation Thresholds (+1)

Correlation Thresholds

Range Interpretation Action
> 0.99 Excellent agreement Solvers validated
0.95 – 0.99 Good agreement Minor differences (phase convention, numerics)
0.80 – 0.95 Fair agreement Investigate input differences
< 0.80 Poor agreement Likely input mismatch or unit error
Negative Anti-correlated Data extraction bug (wrong frequency order, wrong units)

Common Causes of Poor Correlation

  1. Negative correlations: Frequency arrays in different order (ascending vs descending)
  2. Near-zero correlations: Hz vs rad/s mismatch (factor of 2*pi offset)
  3. NaN correlations: Zero standard deviation (all-zero DOF, e.g. yaw for head seas)
  4. Good amplitude, bad phase: Different time convention (e^{+iwt} vs e^{-iwt})
