In the case that a fitting operation fails to converge, consider setting bounds on selected fitting parameters. Although there is no guarantee of a particular fit operation converging, the suggestions below can be useful for certain cases.
Often, once the bounded fit converges, resetting or releasing the bound(s) and fitting again will yield a converged fit as well.
The following fitting functions are mostly used in Peak Analyzer. Some of them may also be used in NLFit.
