More Powerful Tests of the Composite Null Hypothesis Arising in Mediation Analysis

The mediation.test R package implements more powerful tests of the composite null hypothesis arising in mediation analysis. It is developed by A. Chambaz (MAP5, UMR CNRS 8145, Université Paris Cité) & Caleb Miles (Department of Biostatistics, Columbia University Mailman School of Public Health).

Introduction

The mediation_test() function of the mediation.test package tests the composite null hypothesis "δ_x * δ_y = 0" against its alternative "δ_x * δ_y ≠ 0".
