- The aim of this study was to compare periodic and stochastic models generated by using FFT frequencies with periodic and stochastic models generated by using astronomic frequencies. Fourier series were used to simulated periodic model, and autoregressive method was employed to simulate stochastic model. In this study, 253 dominant FFT frequencies and 9 astronomic frequencies were used as constituent frequencies to simulate periodic models. 512 hours of data were used for the model. Results of this study present that the periodic and stochastic models using FFT frequencies gave more accurate results than periodic and stochastic models using the astronomic frequencies.
