Hi, We can compute the sum of factor loadings in mplus software in the CFA example by setting (F1 "BY x1-x6*(p1-p6); MODEL CONSTRAINT: new(H1); H1=(p1+p2+p3+p4+p5+p6);" How can we do in ESEM? I eagerly need this function. I think that other researcher also need this function. Can you write code to achieve this function. Thank you!
