The subroutines in this package estimate parameters in a nonlinear model using the criterion of least-squares. Eight different user-callable subroutines are provided to support different combinations of three options: (1) the method of obtaining derivative values, (2) bounds on parameters, and (3) use of a special algorithm for the separable problem.
