Equations / Aboveground biomass
Gmelin larch AGB from DBH only, unweighted (Table 3)
As printed (Хүснэгт 3 (Table 3), Газрын дээрх биомасс (above-ground biomass), p. 124-126)
In this library's units, ready to compute (kg)
Aboveground biomass = 1.02 * exp(-2.389 + 2.403 * ln(D))D- Diameter at breast height (1.3 m), cm
Paper is in Mongolian; table values quoted as printed. Unweighted (N) regression row; the printed CF is applied as exp(lnŷ) x CF per eq. 8. Adjusted R² and RMSE are in the table but are not stored (adjusted R², and RMSE on the log or weighted scale). AGB is the sum of stem, branch and needle mass (Table 1), so foliage is included. Natural log assumed from the paper's ln notation.

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 = 20 | 125.2 | 125.2 | Computed from the printed form computed from the Table coefficients and the printed back-transform y = exp(lny) x CF (eq. 8) |
| D = 35 | 480.2 | 480.2 | Computed from the printed form computed from the Table coefficients and the printed back-transform y = exp(lny) x CF (eq. 8) |
