WebOct 10, 2024 · So if done properly, changing the duration of the time series should not, if all else is equal, change the amplitude of the transform at any given frequency. Technically, you are most likely computing the fast Fourier transform (FFT) of the input time series, but again the Fourier coefficients (i.e., amplitudes) should be properly normalized.

Kant's argument for finitism has been widely discussed, for instance Jonathan Bennett points out that Kant's argument is not a sound logical proof: His assertion that "Now the infinity of a series consists in the fact that it can never be completed through successive synthesis. It thus follows that it is impossible for an infinite world-series to have passed away", assumes that the universe was created at a beginning and then progressed from there, which seems to assume the conclu… option on futures pricingWebFINITE-TIME ANALYSIS 237 in Theorem 2 for a more complicated version of this policy).
