multiblock (version 0.8.10)

cca: Canonical Correlation Analysis - CCA

Description

This is a wrapper for the stats::cancor function for computing CCA.

Usage

cca(X)

Value

multiblock object with associated with printing, scores, loadings. Relevant plotting functions: multiblock_plots

and result functions: multiblock_results.

Arguments

X

list of input data blocks.

Details

CCA is a method which maximises correlation between linear combinations of the columns of two blocks, i.e. max(cor(X1 x a, X2 x b)). This is done sequentially with deflation in between, such that a sequence of correlations and weight vectors a and b are associated with a pair of matrices.
