Causal Mediation Analysis
A 2-Day Seminar Taught by Tyler VanderWeele, Ph.D.
This seminar will focus on some of the recent developments in causal mediation analysis and will provide practical tools to implement those techniques. Mediation analysis deals with the mechanisms and pathways by which causal effects operate. The course will discuss the relationship between traditional methods for mediation in the biomedical and social sciences and new methods of causal inference for dichotomous, continuous, and time-to-event outcomes.
We will also consider when standard approaches to mediation analysis are valid and when they are not valid. These approaches will be extended to more complex settings. The no-confounding assumptions needed for these techniques will be discussed in detail. SAS, SPSS and Stata macros to implement mediation methods will be demonstrated and distributed to course participants.
Other topics include the use and implementation of sensitivity analysis (to assess how sensitive conclusions are to violations of assumptions) and extensions to multiple mediators.
Who should attend?
Course prerequisites: Familiarity with linear and logistic regression. Some knowledge of counterfactual or potential outcomes notation is helpful, but not necessary. Software descriptions will be given in SAS, Stata, SPSS, and R but knowledge of these is not required for the course.
In all cases, methods will be illustrated using software, with SAS, Stata, SPSS, and R examples and syntax. This is a hands-on course with at least one hour each day devoted to carefully structured and supervised assignments. To do the exercises, you will need to bring your own laptop computer with a recent version of SAS or Stata or SPSS or R.
LOCATION, FORMAT AND MATERIALS
The class will meet from 9 am to 5 pm each day with a 1-hour lunch break at Temple University Center City, 1515 Market Street, Philadelphia, PA 19103.
Participants receive a bound manual containing detailed lecture notes (with equations and graphics), examples of computer printout, and many other useful features. This book frees participants from the distracting task of note taking.
