In TapeR: Flexible Tree Taper Curves Based on Semiparametric Mixed Models
HT.par R Documentation
Height tariff parameters for estimating tree heights of unmeasured
trees in the BWI3.
Description
Height is only measured on a subset of the trees on a sample
plots. This Height tariff is used to estimate the height of the trees
with only a dbh measurement.
Usage
