Hi everyone! Hope that someone knows a workaround to this problem. I have a set of experimental data. The analytical equation that I get returns a real and imaginary parts. The imaginary part is very small and from point of view is insignificant. I would like to fit my experimental data to the real part of the model disregarding imaginary part. NonlinearFit doesn't seem to work in such situation. At the best it returns "the model is not real" which I already know. Is there a way to either modify my model or make NonlinearFit discard imaginary part? Thank you all very much for any suggestions. Michael
