RE: Logistic Fit
Yes, starting values should help to circumvent the "not central about the origin" issue. Coupled with a technique like Levenberg-Marquardt (alternating between Newton and Steepest Descent) works for most data sets - - although local minima might be encountered. I believe that is what is implemented in MODA, and also in MRQ library for the 49/50.
