Compatible Volume-Taper Models for Loblolly and Slash Pine Based on a System with Segmented-Stem

摘要

By integrating a variable-from differential equation for taper, a segmented-stem system of models involving a taper equation, merchantable volume equation, and total stem volume equation results. Through the constraints imposed on the coefficients of integration, the taper model is continuous at the inflection points, and all components in the system are compatible with each other. Models are derived for a bole with two inflection points, but the constant from factor model (no Inflection point) and one inflection point segmented model can be obtained as special cases by Substituting appropriate parameters directly into this more general model.
