Predicting Future Diameter Distributions Given Current Stand Attributes

This study discussed four methods to project a diameter distribution from age A1 A2. Method 1 recovers parameters of the at A2 stand attributes that age. 2 uses stand-level model grow quadratic mean diameter, and then prediction. 3 grows by assuming tree-level survival growth functions. 4 first converts into list individual trees before growing these A2.
 In numerical example employing Weibull distribution, produced better results based on two types error indices relative predictive for each class. is novel method individual-trees, in process, successfully links together individual-tree, whole models.
