Nonlinear Mixed Effects Modeling for Slash Pine Dominant Height Growth Following Intensive Silivicultural Treatments

摘要

A modified Richard's growth model with nonlinear mixed effects is developed for modeling slash pine (Pinus elliottii Engelm.) dominant height growth in conjunction with different silivicultural treatments. All three parameters in the model turn out to have both fixed and random individual plot or silivicultural treatments effects. Moving average correlation with 2 was identified as within-plot error structure.
