is.solutions.PTAk {PTAk}R Documentation

Output object from a PTA-kmodes analysis and other methods implemented in this package

Description

The object class solutions.PTAk is list of list. solutions[[i]] is a list with arguments the following arguments:

Usage

is.solutions.PTAk(solut)

Arguments

v a matrix nb of solutions times dimension of the mode i
modesnam a character object naming the mode, "m i" otherwise
n labels of mode i entries as given in dimnames of the data
-
d singular values
pct local percent of sum of square for the above singular values 100 d^2/ssX
ssX local sum of squares, i.e. for the tensor currently analysed (nested projections of X, ssX[1] is the total sum of squares
smoocheck bolean matrix with k rows and length(vsnam) columns to check if a smooth componnet was computed
vsnam names of the singular values, see details
datanam name of the tensor analysed
method the match.call of the function which gave the resulting solutions.PTAk object.

Details

The object solutions.PTAk is output from PTAk is a list of length the order of the tensor used in the analysis. Each element of the list is a list with the above arguments (the last arguments starting from d are given only for the last member of the list ). For a given row number t the tensor product of the mode components v[t,] time the corresponding d[t] constitute a Principal Tensor of datanam. The corresponding name of the singular value follows the rule: e.g. vs1111, vs2222 are kmodes solutions (4-modes analysis); in a 3-modes analysis 12 vs111 5 12 means an associated solution to the kmodes solutions (vs111) according to the mode of dimension 12, the other dimensions 5 and 12 are given only when the vs results from a 2modes analysis; associated of associated have a form like 9-15 vs1111 10 888 (from a 4-modes analysis).

Value

The class object is a list of a lists with the specified arguments and right dimensions. The class object is used in RESUM, summary, plot, REBUILD, APSOLU3 and APSOLUk.

Note

The function SVDgen output an object of class solutions.PTAk.
