emerson.poly

This function is called from the functions
<code>docabasic, socabasic, sonscabasic</code> and <code>donscabasic</code>. 
It computes the orthogonal polynomials for the ordered categorical variables. 
The number of the polynomials is equal to the number of categories for that variable less one.
The function computes the polynomial transformation of the ordered categorical variable.

nonparametric

Provides six variants of two-way correspondence analysis (ca):
simple ca, singly ordered ca, doubly ordered ca, non symmetrical ca,
singly ordered non symmetrical ca, and doubly ordered non symmetrical
ca.
