step.g3ordered function

The core array derived via the Trivariate Moment Decomposition model.

The Trivariate Moment Decomposition model involves the computation of principal polynomial components, which are derived for each of the three categorical variables, and of the polynomial core array which is akin to the generalised correlations between these components. The function step.g3ordered computes the core array.

step.g3ordered(param)

Arguments

• param: The weighted three-way table and the matrices of the row, column and tube components derived via the Trivariate Moment Decomposition algorithm.

Returns

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