Developing a Model for Curve-Fitting a Tree Stem’s Cross-Sectional Shape and Sapwood–Heartwood Transition in a Polar Diagram System Using Nonlinear Regression

Developing a Model for Curve-Fitting a Tree Stem’s Cross-Sectional Shape and Sapwood–Heartwood Transition in a Polar Diagram System Using Nonlinear Regression

A function from the domain (<i>x</i>-set) to the codomain (<i>y</i>-set) connects each <i>x</i> element to precisely one <i>y</i> element. Since each <i>x</i>-point originating from the domain corresponds to two <i>y</i>-points...
