%description
We implement functions allowing for mediation analysis to be performed in
cases where the mediator is a count variable with excess zeroes. First a
function is provided allowing users to perform analysis for zero-inflated
count variables using the marginalized zero-inflated Poisson (MZIP) model
(Long et al. 2014 <DOI:10.1002/sim.6293>). Using the counterfactual
approach to mediation and MZIP we can obtain natural direct and indirect
effects for the overall population. Using delta method processes variance
estimation can be performed instantaneously. Alternatively, bootstrap
standard errors can be used. We also provide functions for cases with
exposure-mediator interactions with four-way decomposition of total
effect.
