Re: [R] Homals: Nonlinear PCA

Hi Lucia, It is another problem with Homals on my own data. Have you ever got a eigenvalue above one? Because in my analysis homals consistently gave me very small eigenvalues(far below 1), I compared the eigenvalues in Homals and Psych, there were different, Psych always gave me high eigenvalue

[R] Homals: Nonlinear PCA

Hello! I'm using the NLPCA to reduce the dimensionality of nine variables (4 nominal / 3 ordinal /2 numeric) to obtain the object-scores to be used as dependent variable in a regression model. I'm using the package homals (http://www.jstatsoft.org/v31/i04/paper). The output is: Call: homals
