When applying CCA with K (no. components) > 1, the correlations shows that the components (variate pairs) are not in order. I mean the algorithm do not find the components (variate pairs) with highest correlation first as usual with the canonical correlation analysis.

My question is: why this happens? Is there something wrong with the algorithm?

For example:
Cor(Xu,Zv): 0.512428 0.4441759 0.3440325 0.3222489 0.3543843 0.3263363 0.2735624 0.4195671 0.3355198

Hi,

Do you figure out the reason? I have the same doubt about this question.
