What approaches are there to perform FA on data that is clearly ordinal (or nominal for that matter) by nature? Should the data be transformed our are there readily available
R packages that can handle this format? What if the data is of a mixed nature, containing both numerical, ordinal and nominal data?
The data is from a survey where subjects have answered questions of many types: yes/no; continuous; scales. My aim is to use FA as a method for analyzing the underlying factors. I do not yet know what factors I'm looking for. However, condensing the underlying factors into a manageable number of factors is important.
EDIT: Also, can I approximate a survey question answered on the Likert-type scale as a continuous variable?
