Abstract: | The problem of association between two attributes in ap×q contingency table can be looked upon as the problem of relationship between two vector variablesx andy. If there is only one true non-zero canonical correlation betweenx andy, the association between the two attributes is of rank 1 and in this case, one set of scores is adequate to describe the
association completely; these scores are nothing but the coefficients in the canonical variates corresponding to the true
non-zero canonical correlation. Given a set of hypothetical scoresα
1,α1,⋯,αp for the rows, one is interested in testing their goodness of fit. Tests for this are suggested in this paper. For obtaining
these tests, a preliminary result about direction and collinearity factors in discriminant analysis, whenS irrelevant variables are eliminated, is needed. This is derived in part one of this paper.
