T3runsApproxFit: Approximated Tucker3 solutions

Description

Computes all the approximated Tcker3 solutions using PCASup results with r1 (from 1 to maxa), r2 (from 1 to maxb) and r3 (from 1 to maxc) components.

Usage

T3runsApproxFit(X, n, m, p, maxa, maxb, maxc)

Arguments

X

Matrix (or data.frame coerced to a matrix) of order (n x mp) containing the matricized array (frontal slices)

n

Number of A-mode entities

m

Number of B-mode entities

p

Number of C-mode entities

maxa

Maximum dimensionality for the A-mode

maxb

Maximum dimensionality for the B-mode

maxc

Maximum dimensionality for the C-mode

Value

out

Matrix with columns: number of components for the A-mode, number of components for the B-mode, number of components for the C-mode, goodness of fit (%), total number of components
