CORE DEFINITION

In statistics, canonical-correlation analysis (CCA), also called canonical variates analysis, is a way of inferring information from cross-covariance matrices. If we have two vectors X = (X1, ..., Xn) and Y = (Y1, ..., Ym) of random variables, and there are correlations among the variables, then canonical-correlation analysis will find linear combinations of X and Y that have a maximum correlation.

Anchor fast decisions

When studying the relationship between two sets of multivariate variables, high internal correlations within each set can obscure the structure. CCA finds linear combinations of the two sets of variables that maximize the correlation coefficient between these combinations, thereby extracting the strongest association dimensions between the two systems.
