By using suitable parameters, we present a uni¯ed aproach for describing four methods for representing categorical data in a contingency table. These methods include:
correspondence analysis (CA), the alternative approach using Hellinger distance (HD),
the log-ratio (LR) alternative, which is appropriate for compositional data, and the
so-called non-symmetrical correspondence analysis (NSCA). We then make an appropriate comparison among these four methods and some illustrative examples are given.
Some approaches based on cumulative frequencies are also linked and studied using
matrices.
