Mediation analysis with missing data using bootstrap
Four methods for mediation analysis with missing data:
Listwise deletion, Pairwise deletion, Multiple imputation, and
Two Stage Maximum Likelihood algorithm. For MI and TS-ML,
auxiliary variables can be included. Bootstrap confidence
intervals for mediation effects are obtained.
