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
