Abstract :
New periods can emerge from data as a byproduct of incorrect processing or even the method applied. A good way to avoid this error is to use Gauss-Vanicek spectral analysis. It easily detects periods in raw and gapped records, and in physical sciences, it can detect eigenfrequencies and relative dynamics accurately and simultaneously.
