Adaptive Bootstrap Inference for Mediation Analysis with Enhanced Statistical Power R package abima version 1.1 Assess whether and how a specific continuous or categorical exposure affects the outcome of interest through one- or multi-dimensional mediators using an adaptive bootstrap (AB) approach. The AB method allows to make inference for composite null hypotheses of no mediation effect, providing valid type I error control and thus optimizes statistical power.
