loppukerros
Loppukerros is a Finnish term used in measurement science and numerical analysis to denote the remaining discrepancy after a procedure has converged. It represents a final component of total uncertainty that captures error sources not explained by the primary model or calibration equation. Loppukerros can arise from model misspecification, unmodeled dynamics, instrument nonlinearity, or finite-precision arithmetic.
In calibration and data fitting, loppukerros refers to the difference between observed values and true values
The term is common in Finnish-language texts on metrology, statistics, and numerical methods. In English-language equivalents,
