Hi all, I have been encountering an error message when using NonlinearRegress that I have not seen before: "FindFit::fmmp: Machine precision is insufficient to achieve the requested accuracy or precision." My question is, can I still trust the fit it gives me? Or, how would I go about finding a fit that doesn't give this error message? Any thoughts would be greatly appreciated. Best, Catherine
