I am estimating a bifactor model, and want to regress two independent variables (iv1 iv2) on the factors in the model. Furthermore, I want to control for covariates (cv1 cv2). Simplified version of my syntax:

f1 BY i1 i2 i3 i4 i5;
f2 BY i6 i7 i8 i9 i10;
f3 BY i11 i12 i13 i14 i15;
bifactor BY i1-i15;

f1 f2 f3 bifactor ON cv1 cv2 iv1 iv2;

I also want to control for relations between my ivs and covariates and among my ivs. However I do not want to control for cv3 in the regression model and also not for the covariance between cv1 and cv2. I also need WITH statements to include my full sample.

Should I add:
iv1 iv2 ON cv1 cv2 cv3;
iv1 WITH iv2;

iv1 WITH cv1 cv2 cv3;
iv2 WITH cv1 cv2 cv3;
iv1 WITH iv2;
cv1 WITH cv2@0;

Also: would you recommend standardizing ivs and cvs? Also binary variables? Some of my models only work with standardized variables.

Thank you so much for your help.

I know posts should be limited to 1 but I just realized it's important information that I used the WLSMV estimator because of categorical indicators (and my cv2 and cv3 are binary).

I would not use either of your 2 additions.

You may also want to ask on SEMNET.

Thank you. I will ask somewhere else.
