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(-2.2118 + 2.4133 * ln(D))D- Diameter at breast height (1.3 m), cm
Mixed hardwood group; covers American sycamore (Platanus occidentalis) and black cherry (Prunus serotina, spg 0.47) among others. Median specific gravity of the group: 0.47. Diameter range is that of the pseudodata. R² is the published 'R²-statistic'.
