Watanabe-Akaike information criterion [37, 38] comparisons for the distribution of step-size.

Standard and truncated folded-normal, log-normal, and Pareto distributions were considered. The truncated log-normal distribution, with parameters: μ = 0.64 (CI95: 0.60, 0.68), σ = 1.39 (CI95: 1.36, 1.42), and τ = 18.73 (CI95: 18.70, 18.83), outperforms other models in the set. Note here that the μ and σ parameters of the log-normal distribution define, respectively, the mean and standard deviation of the variable’s natural logarithm; the τ parameter defines the variable’s upper truncation point.
