Do I need to create the function I want to fit? Or would I have to look for a function that looks 'similar' to a plot of my data? So say my data 'looks' like a cubic function, I would need to supply it a blank(missing the coefficients) cubic function?
Also thank you for clearing up the mischaracterization.

I recall an example where 7-8 points, trending up, are fitted with a polycurve that sharply dropped right after the last data point thereby giving erroneous prediction.
