Table 4 H-D Model coefficients (a, b, c) of the 2nd order log-log polynomial model form (\({\rm{ln}}\left(H\right)=a+b\times \left({\rm{ln}}\left(D\right)\right)+c\times {\rm{ln}}\left({D}^{2}\right)+\varepsilon \)), where H is the height of the tree and D is the tree diameter. ε is the normally distributed error to be used during back-transformation for Baskerville correction.
