I'm testing a mediational path model using model indirect and bootstrapping. My outcome variable is a count variable so I tried using the (count is) command and I got this error:

" MODEL INDIRECT is not available for analysis with ALGORITHM=INTEGRATION."

Is it possible to combine a Poisson distribution with bootstrapping and model indirect?

The product approach to indirect effects does not work in your case. You can use MODEL CONSTRAINT and the formulas from the following paper:

Muthén, B. (2011). Applications of causally defined direct and indirect effects in mediation analysis using SEM in Mplus

Thank you. I downloaded the paper from the Mplus website but it only goes up to page 110. The info I need is on page 138. Where can I get the whole paper?

The paper has 3 parts - you find the other 2 parts as mentioned in connection with the paper:

"Click here to view the Technical appendix that goes with this paper and click here for the Mplus input appendix."

Page 138 is in the Mplus input appendix.
