Dear Drs Muthen,

I am working on a non-recursive model for multi-level analysis. I typed the following code to represent the non-recursive part (Lat_A affects Lat_B, and Lat_B affects Lat_A). There was no error message. But I was not sure whether I did the correct step.

Would you please give me some hints?
Is this specification valid for both WITHIN and BETWEEN group variables? Thanks a lot.

/* code */

Lat_A BY Lat_A1 Lat_A2 Lat_A3;
Lat_B BY Lat_B1 Lat_B2 Lat_B3;

Lat_A ON Lat_B;
Lat_B ON Lat_A;

/* end of code */

Thanks a lot.

The above model is not identified unless each ON statement has a unique covariate, for example,

Lat_A ON Lat_B x1;
Lat_B ON Lat_A x2;

In addition, the factors need to be defined on both levels.
