Description: This package implements functions for fitting taper curves
(a semiparametric linear mixed effects taper model) to diameter
measurements along stems. Further functions are provided to
estimate the uncertainty around the predicted curves, to
calculate timber volume (also by sections) and marginal (e.g.,
upper) diameters. Uncertainties of single tree volume
predictions resulting from uncertainties in the taper equations
tree height models (tariffs) are provided.  The example data
include the taper curve parameters for Norway spruce used in
the 3rd German NFI fitted to 380 trees and a subset of
section-wise diameter measurements of these trees. The
functions implemented here are detailed in the following

Description: This package implements functions for fitting taper curves (a semiparametric linear mixed effects taper model) to diameter measurements along stems. Further functions are provided to estimate the uncertainty around the predicted curves, to calculate timber volume (also by sections) and marginal (e.g., upper) diameters. For cases where tree
heights are not measured, methods for estimating
additional variance in volume predictions resulting from uncertainties in
tree height models (tariffs) are provided.  The example data include the taper curve parameters for Norway spruce used in the 3rd German NFI fitted to 380 trees and a subset of section-wise diameter measurements of these trees. The functions implemented here are detailed in the following publication: Kublin, E., Breidenbach, J., Kaendler, G.
