Models with Interpolation and Curve
Fitting
16.1 Introduction
The mathematical model in a computational model can be expressed as a set of
polynomial functional equations of any order. If only raw data is available, estimates
of the values of the function can be computed for other values of the independent
variable, within the bounds of the available set of values of the independent variable.
Computing these estimates is carried out using interpolation techniques.
If the mathematical model in the form a polynomial function is needed to repre-
sent the raw data, then curve fitting, also known as regression, techniques are used. In
the general ...
