Dear Linda, dear Bengt, I want to run a CFA for a bi-factor model with correlated latent factors. One latent factor (general achievement; GenAch) is indicated by school grades (v1-v6)and I want to center these indicators at the cluster mean. cluster is "class". And I want to take into account that there is a hierarchical multilevel structure of data (pupils in classes). Is this how I can do it? Variable: [...] cluster=class; centering=groupmean (v1-v6); Analysis: type=complex; model: [...] GenAch by v1-v6*; thanks for your help! |

You have centered and you have taken clustering into account. I don't see a bi-factor model. And if you free all factor loadings as you have done, GenAch by v1-v6*; you must fix the factor variance to one. GenAch@1; |

thanks for your help. Yes, I know about fixing to one. I just send an excerpt of the syntax. the full model is specified as a bi-factor model. my main concern was to clarify the centering question. thanks! |
