Figure 6.

Normalized distributions of the estimations $D_{\text{MSD}}^{\left(1\right)}$, $D_{\text{MSD}}^{\left(2\right)}$, $D_{\text{MSD}}^{\left(3\right)}$, and D_MAP made using the four studied estimators for N = 100 steps and two different values of the confinement level: u = 0.005 (A) and u = 0.05 (B). (MAP estimator, solid green lines; MSD⁽¹⁾, dashed red lines; MSD⁽²⁾, dashed blue; and MSD⁽³⁾, dashed purple.) The vertical black line is positioned at the actual value of the diffusivity ($\tilde{D}=1$ a.u.). The MSD estimators are either biased or less efficient than the MAP estimator.
