public class NonlinearRegressionEx3
extends Object

Fits a nonlinear regression on scaled data.

In this example some non default tolerances and scales are used to fit a nonlinear model. The data is \(1.e-10\) times the data of example NonlinearRegressionEx1. In order to fit this model without rescaling the data we first set the absolute function tolerance to \(0.0\). The default value would have caused the program to terminate after one iteration because the residual sum of squares is roughly \(1.e-19\). We also set the relative function tolerance to \(0.0\). The gradient tolerance is properly scaled for this problem so we leave it at its default value. Finally, we set the elements of scale to be the absolute value of the reciprocal of the starting value. The derivatives are obtained by finite differences.
