I think I could solve the problem myself. This code seems to work (I'm glad if somebody can

Hello everyone, I got an error message when modeling a multilevel mediation model (a 2-2-1 model,

Apologies. I see that this question has previously been answered. One should use the lavTestScore()

Is it possible to constrain the loadings at level 1 across the two groups? Yes, label the parameters

should the last line have been summary(fit1) ? Woops, yes! Terrence D. Jorgensen Assistant Professor,

In the reference group approach (the default in lavaan, I believe), those refer to the comparison

Thanks a lot!! That worked excellently. Didn´t find this solution before so thanks! El lunes, 4 de

Hi Kelly, Ed and Keith correctly described the assumptions of the standard MIMIC model (as well as

I am trying to figure out how I can specify a model with configural measurement invariance, with the

No, we are using theta, but I couldn't come up with a reproducible example, I think it could be

I wasn't aware of the Swain correction. I just added it as a new option to the chisqSmallN()

Thanks so much, Terrence. That fixed it. Brandon On Wednesday, February 5, 2020 at 2:12:36 PM UTC-6,

Olaya-- The model is now fully saturated. With 0 degrees of freedom, the model must fit the data

I should add that if I run the same model without including the general factor, I get the same

Hi, Yu, Sarah, Could you check if this error goes away with Terrence and Yves replies to the thread

The problem is with the correlation matrix: lavaan only accepts covariance matrices (for continuous

Wow, that's easy enough, thanks Christopher! On Monday, June 10, 2019 at 1:12:47 PM UTC-5,

Thanks for a very illuminating answer, I've already started reading the Wu & Estabrook paper!

However, when I run the CFA directly, I get results... If you inspect the syntax, you will notice it

Thank you very much for your help, Dr. Jorgensen! I will definitely try it out. (I'm sorry for

Use lavTestLRT: https://www.google.com/amp/s/rdrr.io/a/cran/lavaan/man/lavTestLRT.html Am 23.05.19,

somewhere I've read that if model fit is problematic, the standardized residual matrix can help

If the observations are related, make them part of the same record, and use equality constraints to
