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. |
