CCA can be considered as a Correspondence Analysis (CA) in which the ordination axis are constrained to be linear ...Q li X = X[i; p] [p]: p=1. Canonical correspondence analysis is realized by a correspondence analysis in which weighted multiple regression is used to represent the axes as linear combination of the explanatory variables. So CCA is a CA with the axes being linear combinations of the explanatory variables. Canonical correspondence analysis.There's no need to send a second message correcting your mistakes.
