(A) Scatter plot of the generalized Hurst exponents h_RR(q) vs. h_mag(q), for healthy and FM groups during daytime periods. For both groups, symbols with error bars represent the mean value, and the error bars the corresponding standard error of the mean. We observe that both groups are well separated for the different values of q. (B) As in (A) but for the generalized Hurst exponents h_RR(q) vs. h_sign(q), for healthy and FM groups during daytime periods. In this case, both groups are close each other for negative moments while tend to be more separated as q increases.
