gsvd {multiblock}

Generalised Singular Value Decomposition - GSVD

Description

This is a wrapper for the geigen::gsvd function for computing GSVD.

Usage

gsvd(X)

Arguments

X

list of input data blocks.

Details

GSVD is a generalisation of SVD to two variable-linked matrices where common loadings and block-wise scores are estimated.

Value

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