Description
Based on the nonlinear least squares method and nonlinear mixed-effects modeling technique, provincial and subregion-specific tree diameter prediction models were developed for major Alberta tree species. These models predict individual tree diameters at breast height from tree heights (varies by report). They can be used at both the population and plot-specific levels with varying degrees of accuracy. Different procedures for making the predictions under different circumstances are presented. Examples of model application are demonstrated based on real data.
