This function is used in the main function `CAvariants`

when the input parameter is `catype = "DONSCA"`

.
It performs the bivariate moment decomposition of the numerator of the Goodman-Kruskal tau index and implies two ordered variables.
It computes polynomial axes, coordinates, weights of rows and columns, total inertia (equal to the numerator of the tau index) and the rank of the matrix.
It allows the analyst to decompose the inertia into row and column polynomial components.
