Fig. 14From: Determination of optimal tree height models and calibration designs for Araucaria araucana and Nothofagus pumilio in mixed stands affected to different levels by anthropogenic disturbance in South-Central ChileThe plot of studentized residuals against the predicted height for N. pumilio. The studentized residuals were obtained by fitting model SM1 NP (a) without weighting, with weight \({w}_{i}=1/DB{H}_{i}^{k}\), where (b) k = 0.5, (c) k = 1, (d) k = 1.5, (e) k = 2, (f) k = 2.5, and (g) k = 3Back to article page
