This function is used by the main function
CAvariants when the input parameter is
catype = "SONSCA".
It performs the hybrid decomposition of the numerator of the Goodman-Kruskal tau index and implies an ordered (column) variable.
It calculates the principal axes for the rows and polynomial axes for the columns, coordinates.
It also calculates the row and column weights, inertia (based on the numerator of the tau index) and the rank of the matrix.
It decomposes the inertia into column polynomial components.
The two-way contingency table.
The set of ordered column scores. By default,
