How to use the Fourier transform function of JMP to fit a list of curve data to the most suitable sinusoid?
For example, in the attachment, I have obtained the "smooth" data of the second column by drawing the smooth line formula of the first column.
The effect of increased "smooth" is to determine the most appropriate sine wave period by repeatedly crossing the two curves.
Of course, the original curve change is completely random, so it can only be required that the fitted sine wave can achieve the maxim...
