Take a numeric vector and return the predicted vector computed as the arithmetic mean of all elements belonging to the same motif.
validate_gmean_byelt_jack(fobs, assMotif, mOccur, jack)
a numeric vector. The vector fobs
contains the
quantitative performances of assemblages.
a vector of labels of length(fobs)
.
The vector assMotif
contains the assembly motifs of assemblages.
a matrix of occurrence (occurrence of elements).
Its first dimension equals to length(fobs)
. Its second dimension
equals to the number of elements.
an integer vector of length 2
.
The vector specifies the parameters for jackknife method.
The first integer jack[1]
specifies the size of subset,
the second integer jack[2]
specifies the number of subsets.
Return a vector of length(fobs)
.
Its values are computed as the geometric mean
of performances of assemblages
that share a same assembly motif,
by excluding a subset of assemblages
containing the assemblage to predict.
Predicted performances are computed
using geometric mean (opt.mean = "gmean"
)
of performances of assemblages
that share a same assembly motif (opt.model = "bymot"
).
The assemblages belonging to a same assembly motif are divided
into jack[2]
subsets of jack[1]
assemblages.
Prediction is computed by excluding jack[1]
assemblages,
including the assemblage to predict.
If the total number of assemblages belonging
to the assembly motif is lower than jack[1]*jack[2]
,
prediction is computed by Leave-One-Out (LOO).
