emerson.poly

This function is called from the function <code>oca3basic</code> when in <code>CA3variants</code> we set 
<code>ca3type = "OCA3"</code>. It allows the analyst to compute the orthogonal polynomials of 
the ordered categorical variable. The number of the polynomials is equal to the variable category less one.
The function computes the polynomial transformation of the ordered categorical variable.

internal

Provides four variants of three-way correspondence analysis (ca):
three-way symmetrical ca, three-way non-symmetrical ca, three-way ordered symmetrical ca
and three-way ordered non-symmetrical ca.
