I am looking for a software tool (preferably open source) to draw structural equation/mixture models efficiently and prettily.
After looking into xfig and graphviz I now stick to the general vector graphics package inkscape because it seems most flexible.
I would like to poll the stat.stackexchange community: How do you draw your structural equation/mixture models? What software do you use?
OpenMx
orlavaan
. These may be great packages per se if you start from ground zero, but unlearning Mplus and learning R/OpenMx is a huge time commitment that I personally would not be prepared to make, the most realistic setting for which could be getting tenured and going on a sabbatical to UCLA :). $\endgroup$
