Average treatment effect estimation
Average treatment effect estimation quantifies the population-average difference in outcomes that would result from two alternative treatments or interventions.
Causal Inference for Data Science
The average treatment effect is the population-average difference in outcomes that would result from two alternative treatments or interventions.
- How it is used
- Quantifies how choosing one treatment, decision, or intervention changes an average outcome versus an alternative.
- How deep it goes
- Develops formulas, confounding adjustment, propensity-score methods, machine-learning estimators, and potential-outcomes notation; defers some derivations to appendices.
- Examples
- Uses recovery under old versus new treatments, age-confounded medication decisions, recommender systems, surgery, and right-heart catheterization data.
- What you can do after
- Apply it via adjustment formulas, propensity scores, and T-learners while checking confounding, overlap, and overfitting.

An average treatment effect is the average difference in an outcome between treated and untreated potential outcomes across a population.
- How it is used
- Quantifies the population-average effect of a specified intervention, such as changing engagement or a recommendation algorithm, on an outcome.
- How deep it goes
- Develops intervention notation, query selection, causal modeling, backdoor adjustment, regression estimation, and an alternative generative-model workflow.
- Examples
- Uses streaming churn and a gaming experiment, then reports a gaming regression estimate with a 95% confidence interval.
- What you can do after
- Apply it via a causal DAG and adjusted linear regression to estimate a specified ATE and inspect its confidence interval.
