There are additional concerns when the either the mediator or outcome variables are binary, and some commentators suggest rescaling (see for example, Krull and MacKinnon). Others have argued that this rescaling does not solve the problem and that the potential outcomes approach is more appropriate (see Imai et al.). I have not seen any more recent literature on the multilevel models with binary mediators/outcomes, or potential outcomes approaches with multilevel data. I hope this helps Ariel References: Imai K, Keele L, Yamamoto T. Identification, inference, and sensitivity analysis for causal mediation effects. Statistical Science 2010;25(1):51-71.

Date: Wed, 25 Apr 2012 10:25:04 +0200 From: Edward Lorenz <Edward.Lorenz@gredeg.cnrs.fr> Subject: st: mediation analysis with multi-level logit models Hello, I am interested in carrying out a mediation analysis with a multi-level logit model. I am using 'xtmelogit' on Stata 11.0 for Mac. My level-2 IV is continuous and the DV and level-1 mediators are binary. I am aware of the Stata program 'binary-mediation' for single level logit models. The bootstrap command is used to compute the standard errors for the direct and indirect effects. Is there a program for multi-level logit models? Thanks for any help on this. * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/ * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
