I was wondering what the difference might be when you create a umx ACEv model and to get the standard estimates (for purposes outside of the likelihood based CIs using umxConfint) you use mxSE on the parameter of interest.
So essentially, doing:
ACE=umxACEv()
umxConfint(ACE, run=TRUE)
^Extract CIs from here (using summary).
Then doing:
mxSE(top.A_std,ACE,run=TRUE)
vs just:
ACE=umxACEv()
mxSE(top.A_std,ACE,run=TRUE)
It appears that by doing it one way or the other I actually get different standard errors. Is there any reason why that might be?
Perhaps additionally important is that I also get different estimates in general from doing it one way or the other? Not sure why that may be, or if it is a product of this issue or related.
EDIT:
I think I made a mistake here! Actually, there doesn't seem to be any difference from what I can tell, just a mix-up. Sorry about that!
One question along the way, though, that I am wondering, is, is there a significant difference between umxConfint and umxCI? It looks like they return essentially (but very marginally different) CIs? And as the CIs are likelihood based, does that mean there are asymmetric SEs, etc. for them, and if so, are those possible to obtain?
Thanks as always!
