simul_data_complete {plsRglm} | R Documentation |
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)
Arguments
totdim |
Number of columns of the X vector (from |
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.
Value
simX |
Vector of explanatory variables |
HH |
Dimension of
the response |
eta |

Note
The value of r
depends on the value of ncomp
:
ncomp | r |

3 | 3 |
4 | 4 |
