Title: | Introduction to causal mediation analysis |
Presenter: | Chuck Huber, Director, Statistical Outreach, StataCorp |
Date: | Sunday, 11 August 2024 |
Time: | 10:00–11:30 a.m. |
Location: | Level 5, 513A of the Palais des Congrès de Montréal |
Description: | Mediation analysis is a statistical technique that is used to parse the direct, indirect, and total effect of an independent variable (X) on a dependent variable (Y) in the presence of a mediating variable (M). This workshop will introduce the concepts of mediation analysis and demonstrate how to conduct mediation analysis using regression and structural equation modeling (SEM). It will also demonstrate how to estimate bootstrap standard errors for mediation models with SEM. Then we will generalize these concepts to causal mediation analysis and show how to estimate direct, indirect, and total effects, as well as potential outcome means (POM) and controlled direct effects for binary, multivalued, and continuous treatments on continuous, binary, and count outcomes with continuous, binary, and count mediators. We will also show how to estimate the effects in odds-ratio, risk-ratio, and incidence-rate-ratio scales along with the proportion mediated. We will conclude by showing how to visualize the results with graphs. |
