Equation
As printed (Table 5 caption, p. 140)
ln(biomass) = β0 + β1 ln(diameter)
In this library's units, ready to compute (kg)
Aboveground biomass = exp(-3.0506 + 2.6465 * ln(D))D- Diameter at breast height (1.3 m), cm
Southern (subsection Australes) high-specific-gravity pines, including loblolly (P. taeda, spg 0.47) and shortleaf (P. echinata, spg 0.47). Fit range only reaches 56 cm. Median specific gravity of the group: 0.47. Diameter range is that of the pseudodata. R² is the published 'R²-statistic'.
