fitting equation

synonym: smoothing equation
https://doi.org/10.1351/goldbook.15328
Theoretically based or empirical equation for interpolation of data over a range of temperature, pressure, composition, or other variable.
Note: The use of a fitting equation for extrapolation of data beyond the equation’s known range of validity is a potential source of extreme error.
