Period_ts | R Documentation |
One of the uses of spectrum density and periodogram is to detect the periodicity of the series. If the spectral density or periodogram or any estimator has a peak at a frequency, the periodicity of the series can be understood. If we reverse the frequency at which the peak is located, the period of the series is obtained.
