Equation

As printed (Methods, H-D relationship)

Allometric equation of the form H = aDb + e, was used to develop the relationship between height (H) with the diameter at breast height

In this library's units, ready to compute (m)

Height = 1.29 * D^1.11

D: Diameter at breast height (1.3 m), cm

Culm-level height model for a bamboo, intended by the authors to fill missing culm heights. D is culm diameter at breast height (cm), H culm height (m); units taken from Table 3 headings, not restated beside the equation. Fitted on 80% of the sample, so n is not stored; Adj. R² is printed but not stored. The paper's biomass models (Tables 5 and 7) predict fresh weight, not dry biomass, and were not added.
