Problem with constraints PreviousNext

Hello all.

I believe I have a problem using constraints.

For example, if I use

[x] (p1);
[x] (p2);
p1 - p2 = 10;

The model acts as if I had put the constraint "p2 = 10;", instead of "p1 - p2 = 10;"

Also, if I use this to set the proportion of class 1


I find out that the constraint is not on the proportion of class 1, but on the "Categorical Latent Variables Mean" of class 1.

You should restate the constraint as:

p1 = p2 + 10;

The value should be a logit.

Thank you, professor Muthen!
