Parameters of simple allometric model are evaluated to derive allometric components of organisms from longitudinal variables.
NULL, or bidimensional
The simple allometric model has the form:
a * cs ^ b, with a,b being constants in
and cs being a sequence of mesures of an organic
component (e.g. the tree-radial increments).
Different allometric variables can be computed;
for the case of tree-radial increments,
c(1,1) produces diameters, and
mp = c(0.25
* pi,2) computes basal areas. The argument
mp can have more than two parameters:
c(a1,b1,a2,b2, ..., an,bn), with
being the number of times that allometric model
will be recursively implemented. Such recursive
evaluation is useful to derive variables which
depend on other allometric covariables: i.e
allometric model would be implemented twice to
recursively compute diameters and tree biomasses
from tree-ring widths. A column of increments of
cs (x) is also computed for further in-package
modeling of relative organic growth from
cumulative organic growth (see
data.frame of computed allometric-organic components and
their correspondent relative increments.
