Hi Mike,
In my stage two analysis I would like to impose equality constraints on some items' error variances in the S matrix to be consistent with the models from the original studies.
I wonder whether this is feasible at all, because here (http://courses.nus.edu.sg/course/psycwlm/Internet/metaSEM/masem.html) you wrote "Since we are conducting a correlation structure analysis, the error variances are not free parameters."
If it is possible, could you please provide a syntax example how to implement the equality constraints?
Many thanks for your help!
Johannes
