Figure 4. Empirical and fitted memory functions of the mobile call sequence (a) Memory function calculated from the mobile call sequence using different Δt time windows.

(b) 1−p(n) complement of the memory function measured from the mobile call sequence with Δt = 600 second and fitted with the analytical curve defined in equation (4) with ν = 2.971. Grey symbols are the original points, while black symbols denotes the same function after logarithmic binning. (c) P(E) distributions measured in real and in modeled event sequences.
