Canonical correlation analysis (CCA) is a statisti-cal method whose goal is to extract the informa-tion common to two data tables that measure quantitative variables on a same set of observa-tions. To do so, CCA creates pairs of linear com-binations of the variables (one per table) that have maximal correlation.Correspondence analysis ( CA) is an extension of principal component analysis (Chapter @ref (principal-component-analysis)) suited to explore relationships among qualitative variables (or categorical data). Like principal component analysis, it provides a solution for summarizing and visualizing data set in two-dimension plots.

Canonical Correspondence Analysis (CCPA)1 is a popular method among ecologists to study species environmental correlations using Generalized Singular Value Decomposition (GSVD) of a proper matrix. CCPA is not so popular among researchers in other fields. Given two matrices Y( n by m) and Z( n by q), CCPA involves computing …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.
