Graphs depict the mean parameter value (solid line) and interquartile range, for a SNR of 40. Note that D * f was constrained to a maximum value equivalent to 1.8× D * f,init in the fit; no change of D * f from 1.8 to 2.0 was expected. These data show that fixing one of the D *’s limited bias in one exponent only. In case only one exponent would be of interest, this could help improve the robustness of the model, without interfering in the f and D * parameter of interest.
