Comparison of Tanner score time profile clustering performed imposing either a 2-cluster solution or a 3-cluster solution. (Top row) 2-way clustering: (a) males, (b) females. (Bottom row) 3-way clustering: (c) males, (d) females. The clustering were obtained with Mfuzz: dark colors represent the group membership, and light blue colors show the trajectories associated to low values of membership according to the fuzzy setting of the algorithm. Mfuzz output is shown here in order to account for the trajectories of uncertain classification.
