Sensitivity analysis for assumptions of general mediation analysis.

ABSTRACT: Mediation analysis is widely used to identify significant mediators and estimate the mediation (direct and indirect) effects in causal pathways between an exposure variable and a response variable. In mediation analysis, the mediation effect refers to the effect transmitted by mediator intervening the relationship between an exposure variable and a response variable.

In addition to the traditional mediation analysis methods, Yu et al. proposed a general mediation analysis method that can use g
