I have a question concerning semTools' EFA function.
Currently I'm working on a project regarding a 27 item questionnaire that was developed but never evaluated.
I decided that an EFA was the way to go and as the items are categorical, WLSMV would be the recommended procedure of estimation as I understand.
After trying different solutions using the fa function of the psych package and the factanal function I found out about semTools' EFA ability and the chance to use WLSMV estimation as was recommended to me.
Now the problem:
The results look fine and everything is pretty close to my former results with the other functions but no matter which estimator I use, the items of one factor produce negative loadings when semTools is used.
This does not happen in any of the other functions.
Additionally, I have a second sample that I want to use to apply CFA and as it seems, there are no negative loadings on the factors either.
Can anyone help? I would really like to use the semTools package for this but at the moment it does not yet seem correct to me...
Thank you all in advance, any help is appreciated!
