Distinguishing Stationary/Nonstationary Scaling Processes Using Wavelet Tsallis -Entropies
Figure 7
Classification of correct power-law signals. Recall that indicates the presence of a fractal noise while designates a non-stationary fractal motion. Left plot shows classification for PSD method, middle plot for the so-called SSC (signal summation conversion), and right plot to the novel wavelet Tsallis -entropies-based method with .
