Would like to check w/ others. If I use FindFit, and use a "dummy" Method, I'm given a list of the valid available methods: Here's my error output: FindFit::bdmtd: Value of option Method -> dummy is not Automatic, \ "Gradient", "ConjugateGradient", "InteriorPoint", "QuasiNewton", \ "Newton", "NMinimize", or "LevenbergMarquardt". >> Hmm. "InteriorPoint" sounds interesting. However, this crashes my Kernal quickly. Was wondering if it happens to others. FindFit[ {9, 18, 31, 48}, a*x^2 + b x + c, {a, b, c}, x, Method -> InteriorPoint] We note that both "InteriorPoint" & "NMinimize" are not listed in Help for "FindFit." But the Help files in 6.0 are so poorly written that it's hard to tell. Method->NMinimize doesn't crash my kernal. A correct/wrong method shouldn't crash the kernel, right? Thanks for any insight. Using 6.0, (trying) Using 5.2 Help files Studying 4.0 Book.
