Fig. 9. Scatterplots of DBH periodic annual increment (PAI) over stem number and stand basal area by stand type. The lines represent the models based on linear regression. TPH is trees per ha, BA is basal area, and Pine and Oak are the dummy variables for stand type. All the coefficients were significant (p < 0.001) except for TPH (p = 0.066). R2adj is adjusted coefficient of determination. Sy‧x is standard error of the estimate. DBH: diameter at breast height.
