Factor Analysis (categorical variables)

Hi everyone,

I need to run a factor analysis on a few nominal variables. They have no defined order, therefore, I cannot use polychoric correlations to create a matrix. My variables are coded such that:

1- respondent
2- husband
3- In laws

and so on. I have eight variables and will need to determine:

1. How many factors
2. The best way to code these variables

I am using Stata MP and my data set has over 10,000 individuals (household level data). Any help with how to run the factor analysis (Scree test, rotations etc) and interpret the results would be greatly appreciated.

Thank you very much.
