Introduction to Causal Inference: Propensity Score Analysis in Healthcare Data
This webinar will focus on learning causal inference approaches in a healthcare data analysis context with a particular focus on explaining the application of propensity score analysis in a real-world data analysis context. The session will outline how these analyses are different than conventional regression methods and will address key assumptions/diagnostics of these models.
Describe the basic concepts associated with causal inference and propensity score approaches
Applying propensity score methods (e.g., matching and inverse probability weighting)
Demonstrate a propensity score analysis using R software and a sample dataset
Explain assumptions and diagnostics of propensity score analyses
Outline some extensions of this approach in solving complex real-world problems in the healthcare data analysis context (e.g., in longitudinal and big-data context).
(extra slides) Discuss the best practices associated with propensity score analyses
Background in causal inference is not required. Attendees should have prerequisite knowledge of multiple regression analysis and working knowledge in R (e.g., basic data manipulation and regression fitting). In the webinar, R will be the primary software package used to demonstrate the implementations.

It is assumed that you have the following software packages installed. Webinar does not provide any installation support. Note that, working on software during the webinar is not mandatory. But if the participant like, they are welcome to browse through the webinar slides (as well as check out other materials) in their own laptop.
