loss1.3ordered function

General loss criterion

This function represents the general loss function on which is based the Trivariate Moment Decomposition and calculates the difference between two arrays, x and xhat, where x is the three-way contingency table and xhat is the reconstruction of this table by means of components and core array.

loss1.3ordered(param, comp.old)

Arguments

• param: The matrices of the row, column and tube components derived via the Trivariate Moment Decomposition model.
• comp.old: The matrices of the row, column and tube components derived in the foregoing iteration of the Trivriate Moment Decomposition algorithm.

Returns

The difference between three-way contingency table and its reconstruction from the Trivariate Moment Decomposition model.
