| is.solutions.PTAk {PTAk} | R Documentation |
The object class solutions.PTAk is list of list.
solutions[[i]] is a list with arguments the following
arguments:
is.solutions.PTAk(solut)
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. |
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).
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.
The function SVDgen output an object of class solutions.PTAk.
