Hello I am fairly new at Mplus and my first time with bifactor models Im am trying to run a bifactor CFA but when I run the two models I am getting the same output which makes me very suspicious. Can you tell me if there is an error in my syntax? Even though I am getting an output it all looks very strange. Thanks so much in advance.
DATA:
FILE = abbrev.txt;
VARIABLE:
NAMES = ID age, agegrp, gender ,eth ,epi, I01-I12;
USEVARIABLES = I01,I02,I03, I04, I05, I06-I12;
CATEGORICAL = I01,I02, I03, I04, I05, I06-I12;
ANALYSIS:
type = general;
estimator = MLR;
MODEL:
General BY I01* I02 I03 I04 I05 I06-I12;
! 4 factors:
f1 BY I02* I07;
f2 BY I09* I10 I11 I12 ;
f3 BY I01* I06 I08;
f4 BY I03* I04 I05;
General@0; f1-f4@0;
General with f1-f4@0;
f1 with f2-f4@0;
f2 with f3-f4@0;
f3 with f4@0;
Output:
STDYX Residual;
! standardized; |

One issue is that to set the metric of the factor in the factor variances, they should be fixed to one not zero.
General@1; f1-f4@1;
If you have further questions, send the outputs and your license number to support@statmodel.com. |
