| Class-specific Between Variable Problem |

I am trying to fit a two-class two level model in twin pairs. The twins are modeled with a known class, the other class is estimated. Any attempt to estimate different between level variances of Y results in the error in the subject line. I can't find anything about it online.
*** FATAL ERROR
CLASS-SPECIFIC BETWEEN VARIABLE PROBLEM. |

Dear Prof. Muthen,
I encountered a similar problem and I was wondering how to solve it. I'm trying to model a two-level multiple group model using the KNOWNCLASS option. My model specification is as follows:
MODEL:
%WITHIN%
%OVERALL%
PSMU ON wave3 wave4;
%c#1%
PSMU ON wave3 wave4 (wb1 wb2);
PSMU (varw_boys);
%c#2%
PSMU ON wave3 wave4 (wb3 wb4);
PSMU (varw_girls);
%BETWEEN%
%OVERALL%
PSMU ON prevoc native;
%c#1%
PSMU ON prevoc native (bb1 bb2);
PSMU (varb_boys);
%c#2%
PSMU ON prevoc native (bb3 bb4);
PSMU (varb_girls);
I would like to free the between-level variance of PSMU across the two classes, but then I get the same error as posted above. How can I solve this issue?
Thank you in advance. |
