Try the package "NonlinearFit"
You can load it by: Needs["Statistics`NonlinearFit`"] Use ??NonlinearFit for a brief explanation, see the book Standard Add- On Packages for further explanation, or see the book Applied Mathematica Getting It Started Getting It Done by Shaw & Tiggs. I have found Shaw & Tiggs to be an EXCELLENT reference.
