I cannot set Method->"NMinimize" inside NonlinearModelFit in Mathematica 7 Mac. I get the following error message: NonlinearModelFit::bdmtd : Value of option Method -> NMinimize is not Automatic, "Gradient",...,"NMinimize", or "LevenbergMarquardt" which clearly does not make sense. Everything works fine with Method->"LevenbergMarquardt". But then, Mathematica is quite lousy at minimizing Chi squared...
