Welcome to the lavaan discussion group. Lavaan is an R package for latent variable analysis.

Note: the first time you post, it may take a while (a few hours, up to a few days) before your post is visible. That only happens the very first time you post, because one of the group owners needs to approve your post. (This is to avoid spam).

standardized parameters don't match between std.lv = T and std.lv = F

No, to be honest I did not double check the factor loadings, but now that you mention it... :D Thanks

help! Model won't run when applying constraint with multiple operations

Thanks for your response. I was able to resolve the issue by setting the constraint as b4^2 = 4*b3*b5

Contraitn ont he first factor loading.

You can mention a variable twice--the parser figures this out. So you can write: F1 =~ NA*V1 + a*V1 +

Partial strong invariance: need help on the model syntax (fixed factor and effects coding)

The reason I am not sure if these models are correct: did I correctly change the constraints to scale

Testing measurement invariance with constrained model parameters.

Hi Edward, That does make sense! And yes, you are correct without treating the variables as ordinal
