I am running a full SEM Which I have 9 observed binary indicators (x1-x11), 3 latent factor (f1-f3), 1 mediating variable (m), 3 confounders (x12-x14) and 1 binary outcome (y) . The model is the Following:
BY f1 x1-x4; f2-BY x5 x8; f3-BY x9 x11;
y ON m f1 f2 f3 x12 x13 x14;
ON m f1 f2 f3 x12 x13 x14;
f1 ON x12 x13 x14; ON f1 f2 f3 x12 x13 x14; ON f1 f3 x12 x13 x14;
Now, if the model is correct from a syntactic point of view, the variable m should be a collider. I was wondering if the estimates of the direct and indirect effects on y that provides Mplus are biased or not?
