Randomization and matching
- Andrew Heiss, “Causal Inference,” Chapter 10 in R for Political Data Science: A Practical Guide (2020) (Ignore the exercises!). Get the PDF here.
- Chapter 4 in Impact Evaluation in Practice1
- Chapters 11 and 13 in The Effect.2 Focus especially on section 13.3 about standard errors. And skim chapter 11; it’s an overview of regression, which we reviewed in session 2, but it also applies the language of DAGs to regression, so look for that specifically as you read.

RCTs, matching, and inverse probability weighting
- The example page on RCTs shows how to use R to analyze and estimate causal effects from RCTs
- The example page on matching and inverse probability weighting shows how to use R to close backdoors, make adjustments, and find causal effects from observational data using matching and inverse probability weighting
