Stem profile plots of the 899 trees used in the current study. Profiles of the trees in the fitting, split-validation and independent-validation data sets are shown in black, red and blue lines, respectively. The yellow line shows the BASE model-predicted tree profile for one of the trees (randomly selected), whose dbh and total height were 47.5 cm and 36.8 m, respectively
