In the package Statistics`NonlinearFit` the functions NonlinearFit and NonlinearRegress are defined. There you can chose Levenberg Marquardt as an option Method->LevenbergMarquardt For further explainations see the online help for the Standard Package Statistics`NonlinearFit`. -- Hendrik van Hees Phone: ++49 6159 71-2751 c/o GSI-Darmstadt SB3 3.183 Fax: ++49 6159 71-2990 Planckstr. 1 mailto:h.vanhees at gsi.de D-64291 Darmstadt http://theory.gsi.de/~vanhees/index.html
