u.eppls {Renvlp}R Documentation

Select the dimension of eppls

Description

This function outputs dimensions selected by Bayesian information criterion (BIC) for the Envelope-based Partial Partial Least Squares.

Usage

u.eppls(X1, X2, Y)

Arguments

X1

An n by p1 matrix of continuous predictors, where p1 is the number of continuous predictors with p1 < n.

X2

An n by p2 matrix of categorical predictors, where p2 is the number of categorical predictors with p2 < n.

Y

An n by r matrix of multivariate responses, where r is the number of responses.

Value

u.bic

Dimension of the Envelope-based Partial Partial Least Squares.

bic.seq

BIC value for dimension from 0 to p1.
