Three-path mediation, dichotomous DV
Structural Equation Modeling

I apologize in advance if this has been covered in another thread, but I couldn't find the answers I needed.
I'm running a three-path mediation analysis with bootstrapped CIs. I'd like to use logistic regression to estimate the final DV and I'm not sure how to do this.
Usevariables are y1 x1 m1 m2 ;
Categorical are y1 x1 ;
Bootstrap = 10000 ;
m1 ON x1 ;
m2 ON m1 x1 ;
y1 ON m2 m1 x1 ;
y1 ind m1 x1 ;
y1 ind m2 x1 ;
y1 ind m2 m1 x1 ;
When I run this, I get estimates that are different from my estimates in Stata. I assume Mplus is giving estimates from probit regressions, but when I specify "Estimator = ML" I get an error message:
"BOOTSTRAP is not allowed with ALGORITHM=INTEGRATION."
(though I haven't specified algorithm=integration)
Any thoughts on what I'm doing wrong?

It sounds like numerical integration is required for your analysis because your mediator has missing data. The BOOTSTRAP option is not available in this case. You should remove BOOTSTRAP and CINTERVAL(BOOTSTRAP).

I don't have missing data on any of the variables.

Then I would need to see the full output to understand the situation. Please send it and your license number to
