Desa'a multispecies AGB from DBH (M1)
As printed (Table 3 (a, b, adj-R2, rRMSE, rBias, AIC))
In this library's units, ready to compute (kg)
Aboveground biomass = 0.298 * D^2.034D- Diameter at breast height (1.3 m), cm
Recommended by the authors for simplicity (DBH only), with M9 for stump diameter. Adjusted R2 0.935. The fits were done on ln-transformed data and the paper says predictions were back-transformed with a correction factor (CF from RSE) for its error statistics, but it does not print the CF or say whether the tabulated a already includes it; no cf is entered. Adjusted R2 is given in the notes, not fit.r2, because it is adjusted.

Shaded: the DBH range the model was fitted on. Other inputs held at the values above.
On every build, the library's form and the paper's own form (in its units) must both give these values within 1%.
| Inputs | Expected | We get | From |
|---|---|---|---|
| D = 10 | 32.2 | 32.2 | Computed from the printed form computed from the published form |
| D = 25 | 208 | 208 | Computed from the printed form computed from the published form |
