Table 2.
Hurst parameters H, as obtained for the detrended data of all 15 considered 1-grams describing social phenomena. The left column lists results as obtained with the AFA, while the right column lists results as obtained with the DFA. The range of values as obtained by AFA is 0.74 ≤ H ≤ 1.33, with the average over all 15 considered 1-grams equalling 
. With DFA, we obtain 0.66 ≤ H ≤ 1.44 and
