Speaker

Dr Gary Chan, Senior Research Fellow, National Centre for Youth Substance Use Research, UQ

Abstract

Randomized controlled trial is the gold standard for causal inference yet it is not always feasible. Multi-wave longitudinal data is increasingly used for causal inference. Standard methods such as regression yield biased results in the presence of time-varying confounders. In this seminar, I will demonstrate using Inverse probability treatment weight (IPTW) and marginal structural model (MSM) to adjust for time-varying confounders. Examples in this seminar will be based on research in psychology, public health and epidemiology, and the analyses will be conducted in R and StatsNotebook.
