Hi all,
I have a (hopefully simple but not stupid) software question
related to factor analysis of dichotomous variables:
Christofferson (1975) described a GLS estimator for the
factorization if dichotomous data based on the marginal
distributions for single items and item pairs. Muthen (1978)
suggested another method based on the same information.
I just need to know: Have these estimators ever been
implemented in some statistical software pacakge?
Thanks a lot for any hint,
Johannes Hartig
