Is there a method to limit (bound) the search for a least-squares fit with FindFit[] in Mathematica 5.2? For example I am using FindFit[] to fit a decaying exponential of the form P1 * Exp[-t/P2] + P3. I know from the experiment that P3 is smaller than the value Mathematica continues to find for that parameter. It would be great if there was a way to bound the search for P3 to help Mathematica properly optimize P1 and P2. Joshua LaForge
