simul_data_complete: Data generating detailed process for multivariate plsR models

Description

This function generates a single multivariate response value \(\boldsymbol{Y}\) and a vector of explinatory variables \((X_1,\ldots,X_{totdim})\) drawn from a model with a given number of latent components.

Usage

simul_data_complete(totdim, ncomp)

Value

simX

Vector of explanatory variables

HH

Dimension of the response \(\boldsymbol{Y}\)

eta

See Li et al.

r

See Li et al.

epsilon

See Li et al.

ksi

See Li et al.

f

See Li et al.

z

See Li et al.

Y

See Li et al.

Arguments

totdim

Number of columns of the X vector (from ncomp to hardware limits)

ncomp

Number of latent components in the model (from 2 to 6)

Details

This function should be combined with the replicate function to give rise to a larger dataset. The algorithm used is a port of the one described in the article of Li which is a multivariate generalization of the algorithm of Naes and Martens.
