step.g3 {CA3variants}

The core array derived via the Tucker3 model.

Description

The Tucker3 model involves the computation of principal components, which are derived for each of the three categorical variables, and of the core array which is akin to the generalised correlations between these components. The function step.g3 computes the core array.

Usage

step.g3(param)

Arguments

param

The weighted three-way table and the matrices of the row, column and tube components derived via the Tuckals3 algorithm.

Value

The core matrix whose the general element can be interpreted as a generalized singular value.
