Is there a pkg for calculating cross-validated (k fold) fit measures for #SEM in #rstats? Seems possible with Mplus http://www.statmodel.com/discussion/messages/9/12127.html?1389902731 …

I run sem powe analyses by hand, easier to specify models than canned power solutions and more flexible..
In theory 1) fit on training data save all parameters 2) fit using test data and constrain all the parameters to those found in (1)

Could be done with a fancy function, but that's one huge model string to auto-generate!
