Dear Professor Muthen,

I am exploring a bifactor model involving 2 specific factors & 1 general factor.My sample involves a population with 5 repeated measurements.Overall, the sample size is 495 (110 missing/ 605).However,I am getting the following error messages
THE MODEL ESTIMATION TERMINATED NORMALLY
THE STANDARD ERRORS OF THE MODEL PARAMETER ESTIMATES COULD NOT BE
COMPUTED.THE MODEL MAY NOT BE IDENTIFIED. CHECK YOUR MODEL.
PROBLEM INVOLVING THE FOLLOWING PARAMETER:Parameter 26, GENERAL BY E1

Could you please let me know where might be the problem?Further, could you please advise, how can I extract Test information function from the model?

Many thanks
Best wishes
Anees

The command I used:
Variable:
Names are
tcid e1 e2 e3 e4 e5 cap1 cap2 cap3 cap4 cap5;
Missing are all (-9999) ;
usev=e1- cap5 ;
categorical=e1 - cap5;
cluster=tcid;
Analysis:
Type = complex ;
PARAMETERIZATION = THETA;
MODEL:
qol by e1-e5* ;
wellbeing BY cap1-cap5* ;
wellbeing@1 ;
qol@1;

general by e1-e5* ;
general by cap1-cap5* ;
general@1 ;
general with qol-wellbeing@0 ;
qol-wellbeing with qol-wellbeing@0 ;

OUTPUT: SAMPSTAT STDYX;
