Dear R users and experts,
I am using Homals to perform categorical PCA on some survey data. The
documentation is a bit obscure, however, I followed the examples.
X is a matrix with ordinal 1-5 Likert scale entries on 24 questions from
about 2500 respondents.
So I run
X.nlpc = homals(X, rank = 1, level = "ordinal", ndim = 10)
to get the first 10 pc's (the number of dimensions is irrelevant to my
problem).
I happen to get eigenvalues in nondecreasing order and I am not sure how to
interpret this. Can someone help me?
By the way, I would also be interested in knowing if someone has ever
compared the homals solutions with the ones from the categorical
quantizations performed with the Aspect package.
And, yes, I wrote to package maintainer but I didn't get an answer.
Thanks in advance. Marco
