Subject: Which method to use in Proc CALIS using a polychoric corr matrix
Content-Type: TEXT/PLAIN; charset=US-ASCII
I am trying to use a polychoric correlation matrix and put this as
input to Proc CALIS. Then, my question is: Which METHOD is the most
appropriate for this analysis?
The on-line manual suggests to use METHOD=ULS. But, one professor
suggested to me that I use METHOD=GLS. I am now a bit confused. There may
be no strict rule on this. But I would really appreciate it if you give me
any thoughts and suggestions regarding what METHOD to be used and
your reasoning and justification for it. Thanks.
