Paired t-test presented in Table 5 supports the CI discussed
above. At 95% CI, the mean of the observed and the proposed
models are significantly lower than the mean of the models of
Brown (1997) and Chave et al. (2005), but higher compared to that
of Ketterings et al. (2001).
With regards to GPG (Appendix 4A.2), the developed model can
be used to complement the existing equations by Brown which are
used in GPG.
