Does lavaan support this sort of thing? Last I knew (which was some years ago now), there was no consensus on how to create proper interaction terms with latent variables. Is this still the case? The page gives guidance on how to examine interactions with latent variables in MPlus: http://www.offbeat.group.shef.ac.uk/FIO/model3latent.htm
The key section of the MPlus code seems to be this:
! Create latent interactions
XW | X XWITH W;
XZ | X XWITH Z;
WZ | W XWITH Z;
XWZ | XW XWITH Z;
Any idea how MPlus is creating latent interactions? Can this be doen in lavaan? In R?
For context, I'm reviewing a dissertation where the student used this sort of analyses / syntax. The results look funny and I'm trying to pinpoint why. I'm hoping that replicating the student's analyses in R will help, but I'm not sure if that is possible.
