The numeric vector fobs
get together the properties
of assemblages belonging to different assembly motifs. The properties
fobs
of assemblages belonging to a given assembly motif and
containing a given component are separately averaged. The property of
each assemblage is computed as the average of mean values of assemblages
containing the same components as the considered assemblage. The
motif of each vector component is specified in the vector
assMotif
.
The componental composition of each assemblage is specified in the
binary matrix mOccur
: 0
if the component does not occur,
1
if the component occurs.

a matrix of occurrence (occurrence of components).

Modelled performances are computed
using geometric mean (opt.mean = "gmean"
) of performances.
Modelled performances are the average
of mean performances of assemblages
that share a same assembly motif and
that contain the same components
as the assemblage to calibrate (opt.model = "byelt"
).
This procedure corresponds to a linear model with each assembly motif
based on the component occurrence in each assemblage.
If no assemblage contains component belonging to assemblage to calibrate,
performance is the mean performance of all assemblages.
Return a vector of length(fobs)
.
Its values are computed as the average
of mean performances of assemblages
that share the same assembly motif
and that contain the same components
as the assemblage to calibrate opt.model = "byelt"
.

by assembly motif.
