On the Normalization of chi^2 based Contingency Indices

Antonio Mango

Abstract

In this paper a new way to construct a chi2 based contingency coefficient other than Cramer's V2 and Tschuprov's T2 is proposed. The author explains his point of view on the opportunity to select a particular element of the Class of Frechet, to which the table of contingency under analysis belongs, to get the maximum value of chi2. Both a manual way and a computational one are exposed to obtain the maximum contingency table.
