Re: Fourier transform?
I can think of MANY reasons to do a fourier transform in a spreadsheet, and I have done fourier transforms on data MANY times.
It spots cyclical trends. That's why.
CYCLICAL TRENDS are important, naturally occuring. Seasonality is a good example of ONE cyclical trend, people buying certain kinds of things at Christmas time. Yeah I called it Christmas instead of "winter holidays" and a big F.U. to people who want to complain about it.
So yeah, Fourier Transforms, a welcome feature.
Point is, if I do a spreadsheet of sales data per month, or per day even, and run a fourier transform on it, I might be able to spot trends that can affect how my financial decisions are made.
