I was wondering, how similar or different is umxACEv as compared to umxSexLim (the closest of umxSexLim being the homogeneity choice)? Are they both using the direct variance approach (I know it says for umxSexLim it says it is based on a correlated factors model)? If they are in fact different in that sense, is there a tradeoff between them in that sense (correlated factors vs direct variance)? Definitely would be helpful to know!
Thanks as always!
