Hybrid Formula combines a regression model with a rule-based threshold adjustment, blending statistical math with process engineering knowledge.
Use Hybrid Formula when:
Use Hybrid Formula when:
- Data is limited (fewer than 50 samples)
- The process has known physical limits or breakpoints
- A single variable dominates behavior above/below a threshold
- You want more stable predictions in noisy environments
