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.
