Fig. 5

Measured and predicted WBD (g/cm3) (top two) and Residuals plotted against measured Density (g/cm3) (bottom two) in the 90° angles and mixed angle model of multiple tree species using the Rep-selected NIR spectra. Rep_var: variables selected by Rep algorithm; Error bars for predicted values represent the standard deviations obtained from the 200 simulated models
