Fit to Initially Linear Section with Saturation
Description
The standard polynomial fit to a set of data points (x_i,y_i) with the least-squares
minimization of the deviations in y may exhibit oscillations of the fitting curve
which do not match the smooth transition from a linear behavior into a saturation regime.
The rational polynomials are another family of fitting functions; if their numerator and denominator
polynomials have the same degree, they better represent behavior where x approaches
constant values if y becomes large.
A C++ program is provided which implements both types of fits
for data pairs read from an ASCII file.
