Abstract
Distant-independent, individual-tree, diametar growth models were constructed to update information for forest inventory plots measured in previous years. The models are nonlinear in the parameters and were calibrated weighted nonlinear least squares techniques and forest inventory plot data. Analyses of residuals indicated that model predictions compare favorably to another regional diameter growth model and may be considered unbiased for their intended application. In addition, the models provide for estimation of model prediction uncertainties and may be easily recalibrated, The final model calibrations were by species within each of three ecological provinces in the North Central United States.
