Update ACE model in documentation
Fri, 08/21/2009 - 11:23 — mspiegel
The following model has been updated in the /demo directory, but not in the documentation. The AE model should be created by modifying the sub-models. On the documentation page, currently the super-model is being modified to create the AE model (this doesn't work).

This has been fixed in r779 of the repository. Some magic needs to happen to get the fix to the website.

With respect to
mzModel <- mxModel(mzModel,
mxPath(from=c("A1","C1","E1"), to="bmi1", arrows=1, free=c(T,F,T), values=c(.6,0,.6), label=c("a","c","e")),
mxPath(from=c("A2","C2","E2"), to="bmi2", arrows=1, free=c(T,F,T), values=c(.6,0,.6), label=c("a","c","e")))
this change to the model can be put more succinctly:
mzModel <- mxModel(mzModel,
mxPath(from=c("C1","C2"), to=c("bmi1","bmi2"), arrows=1, free=F, values=0, label="c"))
and likewise for the dzModel. It's still a bit more wordy than Mx1's "Drop Y 1 1 1" or the desired OpenMx command mxDrop(mzModel,"c"). If such syntax doesn't automatically propagate across models (which would be a problem for the heavy duty multiple group users) then mxDrop(list(mzModel,dzModel),"c") might be useful.
