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(-2.4108 + 2.4177 * ln(D))
D
Diameter at breast height (1.3 m), cm

Yellow buckeye and basswood (including white basswood, T. americana var. heterophylla). Median specific gravity of the group: 0.32. Diameter range is that of the pseudodata. R² is the published 'R²-statistic'.
