THA-C13 · report metric dependent superiority
Classification and audit outcome: report metric dependent superiority; supported.
Finding
Best model is ambiguous: MLR had the narrowest limits of agreement, whereas random forest had a lower MAE.
Current amendment or qualification
The best-agreement multiple linear regression model had MAE about 4.2 degrees and limits-of-agreement width 26.8 degrees. Random forest had lower MAE (3.2 degrees), so model superiority depends on the error metric.
Integration note: Say best by agreement width; RF is better by MAE.

Original audit locator(s): P261; P262
Audit corrections describe the report only where that classification is explicit. A disagreement within a study, missing protocol, statistical query, access upgrade or optional addition is not silently converted into a report error or a new clinical threshold.
