Variance of random walkers in continuous time with varying values of α/2, and Mittag-Leffler distributed waiting times with μ = 0.75, τ₀ = 1, t_end = 10³, and N = 10⁴. The blue dashed line shows $Var\left[{\overline{X}}_{\mu }(t)\right]\propto t^2$. The red dotted line shows $Var\left[{\overline{X}}_{\mu }(t)\right]\propto t$.
