Figure 8From: Tailor-made composite functions as tools in model choice: the case of sigmoidal vs bi-linear growth profilesAnalysis of a velocity field from an A. thaliana root. (A) A 6-parameter step-stool function lacking the parameter q (red) and the 4-parameter Richards function (blue) were fitted to the velocity data (gray dots; n = 2729).
