Description

Selects among three-mode principal component models of different complexities.

Usage

DimSelector(out, n, m, p, model)

Arguments

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

n

Number of A-mode entities

m

Number of B-mode entities

p

Number of C-mode entities

model

Kind of model (1 for Candecomp/Parafac, 2 for Tucke3, 3 for Tucker2, 4 for Tucker1
