Re: CFA not converging (correlated factors, overlapping item

Hello

Well, I discussed my dilemma on the Lavann group, and it seems that we need a dataset of 28,000+ to get a really relevant CFA analysis using standard procedures, for this type of complex analysis we are looking for.

Thank you very much

Re: CFA for a complex factor structure and a 2,000+ dataset

Hello Yes, it's convergence it seems. The software works well. Thank you. Now, about convergence, to test if the sample size is not enough, I duplicated the sample just to see if a larger sample would solve the convergence issue, but even using a dataset of 8,400 entries the model did not converge. ...

Re: CFA for a complex factor structure and a 2,000+ dataset

Hello Jonathon Well, after I introduced the factors (15), with 50-100 overlapping items each, the report on the right side either displays as working and working without any results being displayed (I left it for a few hours one day), or it displays the message "Iavaan ERROR: fit measures not a...

CFA not converging (correlated factors, overlapping items)

Hi I am working on a research paper using a questionnaire with 237 items, grouped in 15 factors (developed using an EFA), and now we want to do a CFA, for publishing the paper, but Jamovi got stuck (2,266 people in the dataset). All 15 factors have overlapping items (items that belong to more than o...
