Does anyone know of a step-by-step guide for the practical implementation of Gifi Methods for Optimal Scaling in R: The Package homals? Although I have an OK theoretical understanding (thanks chl for directing me to articles), I'm a tech novice and some of the language/technical information is a bit too complicated for me. On that note, can I do the same thing within SPSS??

With regards to SPSS, I believe you need the Categories add-on module.
- SPSS White Paper has further information including lots of references.

(+1) Thanks for reiterating the need to read the R vignette. Nothing's missing there. And for a more thorough understanding of it, all preprint/draft papers that sit on Jan's website, http://gifi.stat.ucla.edu/ – chl Oct 27 '10 at 09:28
