Fig. 15From: 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 Eq. 3 without weighting (left) and with weighting factor \({w}_{i}=1/DB{H}_{i}\) (right)Back to article page
