Factor analysis on ordinal & nominal data

Josip
Hi,

are there readily available R packages that are able to perform FA on
ordinal and/or nominal data?
If not, what other approaches and helpful packages would you suggest?



BR,
Jay

If by ordinal and nominal you mean just a few categories (e.g., a
mood scale or personality item), then try irt.fa in the psych package
or find the polychoric correlations and use any factor analysis
function (e.g., fa in psych, factanal in core R).
