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(-1.8011 + 2.3852 * ln(D))D- Diameter at breast height (1.3 m), cm
Fitted for the Aceraceae ≥ 0.50 spg taxon, which held only sugar maple equations, so it is recorded as a species fit. Median specific gravity of the group: 0.56. Diameter range is that of the pseudodata. R² is the published 'R²-statistic'.
