Hi, I need to include correlated errors terms in my Model Constraints to implement Raykov's 2009 reliability formula. I have the rest of the MPLUS code from his 2010 book. How does one label the pairwise correlations between error terms? I couldn't find anything about them in the MPLUS manual, just how to label error variances.
Thanks!

u1 WITH u2 (p);
labels a residual covariance if u1 and u2 are dependent variables. |

What about the case of u1-u3 WITH u1-u3, where there are three covariances? It accepts the syntax but I'm not clear how the labels are mapping onto the covariances. It occurs to me that a possible alternative is to use the PWITH command to specify the pairs explicitly so that each can be labeled individually but it'd be easier if I could just use the WITH approach.
Thanks!

| Which covariances do you actually want? You cannot identify all of them. |
