Abstract :
A discussion and evaluation of the Vector Fitting technique is presented, in comparison with a special flavor of the Levenberg-Marquardt method, which is one of the most successful quasi Gauss-Newton techniques. Although generally slower than Vector Fitting, the Levenberg-Marquardt method can achieve greater accuracy than Vector Fitting, because of its unique ability to navigate between local minima.
