Data requirements
Le modèle 4PL exige au moins 4 étalons valides et le 5PL au moins 5. Les concentrations doivent être positives et les DO numériques.

Reviewed 12 August 20264PL/5PL calibration and inversion review complete
Implementation check
The analysis preserves standard observations, fits a selected logistic calibration model and flags unknowns that cannot be inverted to a supported concentration.
Interpretation boundary
Only report concentrations within a method-supported range. Curve fit alone does not establish calibrator acceptance, matrix suitability, dilution integrity, accuracy or precision.

REFERENCE VALIDATION CASE
Synthetic logistic calibration
Forward-generated response inverted with the same 4PL calibration model.
Inputs
- Noise-free 4PL standards
- Unknown response generated at 50 concentration units
- Unknown inside the standard range
Expected result
- 4PL fit reproduces the calibration trend
- Interpolated unknown approximately 50
- No out-of-range warning
Scope: Does not replace run acceptance, matrix, accuracy or precision criteria.
