Take a vector fobs of assembly performances
and return a vector of performances
predicted as the arithmetic mean
of performances of all assemblages.
All assemblages share the same assembly motif.
amean_bymot_LOO(fobs)a numeric vector. The vector fobs contains the
quantitative performances of assemblages.
Return a vector of length(fobs).
Its values are computed as the arithmetic mean of performances,
by excluding the assemblage to predict.
Predicted performances are computed using arithmetic mean
(opt.mean = "amean") of performances of assemblages
that share a same assembly motif (opt.model = "bymot")
by excluding the assemblage to predict.
amean_byelt_LOO arithmetic mean
by elements occurring within assembly motif
gmean_bymot_LOO geometric mean by assembly motif
gmean_byelt_LOO geometric mean
by elements occurring within assembly motif
