Unfortunately, no.  However, you can follow our algorithm if you are able to program it.

Dear Dr. Imai,

is there a way to run a survival analysis with random effects in your mediation package?

Thanks,

Eduardo

It sounds like you want to do the moderated mediation: see Section 3.2 of this paper http://imai.princeton.edu/research/files/mediationR2.pdf

Kosuke

I am doing a mediation meta-analysis and I am trying to use your software.

The problem is that I have several different studies with somewhat different treatments that all affect the same mediator, and the same outcome but affect them differently.  A reasonable model would have to contain a treatment-study interaction.  I can't figure out how to do that with your R package.
I am trying to estimate the Proportion Mediated and associated p-value and confidence intervals,

I would appreciate any help you would give.

Thanks
