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. ----- Mark Difford (Ph.D.) Research Associate Botany Department Nelson Mandela Metropolitan University Port Elizabeth, South Africa -- View this message in context: http://r.789695.n4.nabble.com/How-to-use-PC1-of-PCA-and-dim1-of-MCA-as-a-predictor-in-logistic-regression-model-for-data-reduction-tp3750251p3755163.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
