[R] Correspondence analysis/optimal scaling with ordinal variable

[Andrew Criswell]

Dear Marco:

Alan Agresti in "Categorical Data Analysis," p. 291-3 describes the use of
correspondence analysis and provides an example.

Laura Thompson in "Splus Manual to Accompany Agresti's Categorical Data
Analysis" implements Agresti's example on p. 45-6. Some slight modifications
will render the example in R.  Her paper can be found on

http://math.cl.uh.edu/~thompsonla/5537/Splusdiscrete.PDF

This might be of benefit to your work.

Best wishes,
ANDREW
