    Hello,

    I am running a multilevel CFA model where I need to constrain the diagonal of the between-level residual variance-covariance matrix to be zero. I know how to do it in Mplus(“y1-y5@0” as shown below), but I am not sure how to do it with xxm. I am new to R and xxm. Any thoughts or suggestions are greatly appreciated! Thanks in advance for your help.
