Total Information in Multivariate Data from Dual Scaling Perspectives
Nishisato, Shizuhiko
Alberta Journal of Educational Research, v49 n3 p244-251 Fall 2003
It is an established matter that the total information in multivariate data is defined as the sum of eigenvalues of the variance-covariance matrix. In this article, we challenge this time-honored tradition and look at another definition of the total information in data from a dual scaling perspective. This proposal is a step toward unifying the concept of information for both discrete and continuous variables.
