CANSSI National Seminar Series (DSAS)

Speaker: Dr. Linbo Wang (UoT)

Students are invited to also sign up for an informal Q&A with the speaker on the same day from 3:00pm - 4:00pm EST. This is a great way to network with someone who has a wealth of experience working in academia and get advice on our next career steps. 

Title: The Promises of Multiple Outcomes

Abstract: Unobserved confounding presents a major threat to the validity of causal inference from observational studies. In this paper, we introduce a novel framework that leverages the information in multiple parallel outcomes for identification and estimation of causal effects. Under a conditional independence structure among multiple parallel outcomes, we achieve nonparametric identification with at least three parallel outcomes. We further show that under a set of linear structural equation models, causal inference is possible with two parallel outcomes. We develop accompanying estimating procedures and evaluate their finite sample performance through simulation studies and a data application studying the causal effect of the tau protein level on various types of behavioural deficits.
