AIC = Akaike information criterion; RMSE = root mean squared error; R2 = coefficient of determination; R2adj = coefficient of determination adjusted for the number of terms; SSE = sum of the squared errors.

The growth functions preceded by an F represent the female models, while the functions preceded by an M represent the male models. The statistical measurements for each global fit are shown. There were 31 female and 33 male scans in the data set.
