RobustMediate: Causal Mediation Analysis with Diagnostics and Sensitivity
Analysis
Provides tools for causal mediation analysis with continuous
treatments using inverse probability weighting (IPW). Estimates natural
direct and indirect effects over a user-defined treatment grid and supports
flexible dose-response mediation analysis. Includes diagnostic procedures
for assessing covariate balance in both treatment and mediator models using
standardized mean differences. Implements pathway-specific extensions of
the impact threshold for a confounding variable (ITCV; Frank, 2000
<doi:10.1177/0049124100029002001>) adapted to mediation settings. Provides
joint sensitivity analysis combining E-values (VanderWeele and Ding, 2017
<doi:10.7326/M16-2607>) and violations of sequential ignorability (Imai,
Keele, and Yamamoto, 2010 <doi:10.1214/10-STS321>). Additional utilities
include visualization of dose-response mediation functions, robustness
profiles, fragility summaries, and formatted outputs for applied research.
Supports clustered data structures and multiple outcome families.
