I have nicely fit an exponential function to my data and want to get the literal prediction expression. However, the prediction expressions on the Specialized Modeling --> Nonlinear platform only seem to be in a generalized sense.
How do I get the actual values, as I would in something like the Fit Y by X platform? I did use the Fit Y by X to get actual values for the equation and found that I needed to specifically fit a 3rd degree exponential, but the fit wasn't as nice looking as with the Nonlinaer platform.
