A Study on the Heterosceasticity in Tree Biomass Model

    Graphical Abstract
    • Abstract
  • Validation on Larix olgensis showed that the error of tree biomass model is heteroscedastic. Thus, a parameter estimate method where the heteroscedasticity is overcome by the model itself as weight function was proposed.
