Dear Dr. Muthén,

I am running a mediation analysis in LGCM framework. I wonder whether bootstrap with CI for the mediation effect is available for categorical outcomes using ML(R) estimator?

Many thanks in advance,

Caiyan

Mplus Version 7.2 added bootstrap with numerical integration - which is what ML(R) calls for with categorical outcomes.

There is a follow-up question that I want to ask. How to use model constraint command to specify and test the indirect effect when there are multiple pathways from X to the mediator? More specifically, in multiple growth process where growth factors in latent growth curve models are used as x(i1,s1) and mediator(i2,s2).


MODEL: ...snip..
i2 on i1;
s2 on s1;

outcome on i2;
...snip...

You simply have several a*b parts, one for each X and M. They can be added up for a total indirect effect.
