SIMPLS-CA: SIMPLS Canonical Analysis

Description

The function simplsca performs the SIMPLS Canonical Analysis algorithm as described in Michel Tenenhaus book La Regression PLS, chapter 5.

Usage

  simplsca(X, Y, comps = 2)

Arguments

X

Numeric matrix or data frame with two or more columns (X-block).

Y

Numeric matrix or data frame with two or more columns (Y-block).

comps

Number of components to be extracted. (TRUE by default).

Details

No missing data are allowed.

Value

An object of class "simplsca", basically a list with the following elements:

x.scores

scores of the X-block (also known as T components)

x.wgs

weights of the X-block

y.scores

scores of the Y-block (also known as U components)

y.wgs

weights of the Y-block

cor.xt

correlations between X and T

cor.yu

correlations between Y and U

cor.xu

correlations between X and U

cor.yt

correlations between Y and T

cor.tu

correlations between T and U

R2XT

explained variance of X by T

R2YT

explained variance of Y by T

R2YU

explained variance of Y by U

R2XU

explained variance of X by U
