Distinguishing Stationary/Nonstationary Scaling Processes Using Wavelet Tsallis 𝑞-Entropies

Figure 1

Sample path realizations of some scaling processes. Top left depicts a fGn with 𝛼=−0.1, top right a PPL process with 𝛼=−0.1, bottom left plot a fBm signal with 𝛼=1.9, and finally bottom right plot a PPL process with 𝛼=1.9.
