Hi, I'm conducting an eval of partial measurement invariance using a multiple indicator growth model. I ran the full model in the equal factor loadings and the data did not fit. Upon a suggestion, I freely estimated one of the factor loadings - I want to be sure I have the syntax correct:

W1 BY posit1
totsubd1 (1);
W2 BY posit2
totsubd2 (1);
W3 BY posit3
totsubd3 (1);
W4 BY posit4
totsubd4 (1);

So, this would set posit1-4 as the marker, freely estimate ysr1-4 and the constrain totsub1-4 to equality enabling the examination of equal factor loadings. Then, when I conduct the equal indicator intercepts model, I only include the following:
[posit1 posit3 posit3 posit4] (2);
[totsubd1 totsubd2 totsubd3 totsubd4] (3);
[w1@0 w2 w3 w4];
and not include the [ysr1-4]...right?

You can include it but without the equality label.
