But then, there is the data issue: should it be time-series,
cross-sectional or panel (that is, time-series/cross-sectional)?

If it is time-series or panel, what should be the observation
frequency: yearly, monthly, hourly, every other secondly or shorter or
way longer than yearly?

If it is cross-sectional or panel, how large should be the
cross-section: five persons, 5,000 persons, 5,000,000 persons, the
entire human population currently alive and lived in the past?

How about fitting a two-dimensional Fourier Series to an infinitely
long-infinitely broad data?

The fit would be perfect, but would it explain or predict anything?

Best,
Sabri
