Is there any mplus tutorial/notes or mplus application paper on multiple group(knownclass) parallel process gmm or lcga. I am having difficulty with the loglinear parametrization because my model is

process1 WITH process2;

Process1 process2 ON knownclass_variable;

Changing the WITH statement to ON would work OK with logit parameterization but the processes will be sequential-like instead of parallel.

Any worked out example or methodological paper would be helpful.

Thanks
