canocor {calibrate}

Canonical correlation analysis

Description

canocor performs canonical correlation analysis on the basis of the standardized variables and stores extensive output in a list object.

Usage

canocor(X, Y)

Arguments

X

a matrix containing the X variables

Y

a matrix containing the Y variables

Details

canocor computes the solution by a singular value decomposition of the transformed between set correlation matrix.

Value

Returns a list with the following results

ccor

the canonical correlations

A

canonical weights of the x variables

B

canonical weights of the y variables

U

canonical x variates

V

canonical y variates

Fs

biplot markers for x variables (standard coordinates)

Gs

biplot markers for y variables (standard coordinates)

Fp

biplot markers for x variables (principal coordinates)

Gp

biplot markers for y variables (principal coordinates)

fitRxy

goodness of fit of the between-set correlation matrix

fitXs

adequacy coefficients of x variables

fitXp

redundancy coefficients of x variables

fitYs

adequacy coefficients of y variables

fitYp

redundancy coefficients of y variables
