Hi Kohkichi,
Yes, but maybe explore the "sets=" argument (set "Response" as the target
variable and the others as the predictor variables). Then use Dim1 scores.
Also think about fitting a rank-1 restricted model, combined with the sets=
option.
See the vignette to the package and look at
@ARTICLE{MIC98,
author = {Michailides, G. and de Leeuw, J.},
title = {The {G}ifi system of descriptive multivariate analysis},
journal = {Statistical Science},
year = {1998},
volume = {13},
pages = {307--336},
abstract = {}
}
Regards, Mark.
