Three-path mediation, dichotomous DV |

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. y1=dichotomous x1=dichotomous m1&m2=continuous (Abridged) code: Usevariables are y1 x1 m1 m2 ; Categorical are y1 x1 ; Analysis: Bootstrap = 10000 ; Model: m1 ON x1 ; m2 ON m1 x1 ; y1 ON m2 m1 x1 ; MODEL INDIRECT; y1 ind m1 x1 ; y1 ind m2 x1 ; y1 ind m2 m1 x1 ; OUTPUT: cinterval(bcbootstrap) ; 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? Thanks! |

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 support@statmodel.com. |
