H= height (m); (m); D = diameter at breast heightThe interaction effects in the stand density and web-site index can considerably improve the prediction accuracy of the height-diameter model as the predicted efficiency of interactive NLEM height-diameter model (Equation (13) with R two = 0.6234) was much better than the NLS model (Equation (12) with R 2 = 0.5717). In practical application, it can be normally necessary to think about the effect from the interaction effects in between the predictors on the estimated variable. Consequently, researchers in other disciplines can refer for the interactive NLME height-diameter model presented in this article to build the interactive NLME model. However, it may be observed in the residual plots (Figure 4) on the interactive NLME height-diameter model that, compared with large-diameter trees, the height of small-diameter trees varies largely, which could possibly be for the reason that the trees first focus on the height development to win glory and after that use their sources to boost the diameter [7]. To a certain extent, the altitude may perhaps influence the impact of your interaction effects involving the stand density and website index on tree height, which requires additional experiments to prove. In our data, the fitted height curves of Larix olgensis had been naturally PW0787 Agonist different at various altitudes (Figure six), and this indicates that the altitude could affect the the fitting curve of Figure The fitting curves of height-diameter partnership at different altitude levels.
