Introduction If you have studied causal inference before, you probably already have a solid idea of the fundamentals, like the potential outcomes framework, propensity score matching, and basic difference-in-differences.

The Details

But, foundational methods often break down when it comes to real-world challenges. Sometimes the confounders are unmeasured, treatments roll out at different points in time, or effects vary across a population.

This article is geared towards individuals who have a solid grasp of the fundamentals and are now looking to expand their skill set with more advanced techniques. To make things more relatable and tangible, we will use a recurring scenario as a case study to assess whether a job training program has a positive impact on earnings.

Why This Matters

This classic question of causality is particularly well-suited for our purposes, as it is fraught with complexities that arise in real-world situations, such as self-selection, unmeasured ability, and dynamic effects, making it an ideal test case for the advanced methods well be exploring. The most important aspect of a statistical analysis is not what you do with the data, but what data you use and how it was collected. — Andrew Gelman, Jennifer Hill, and Aki Vehtari, Regression and Other Stories Contents Introduction 1.

This adds to the ongoing AI race that’s captivating the tech world.

The Bottom Line

Sensitivity Analysis: The Honest Researchers Toolkit Putting It All Together: A Decision Framework Final Thoughts Part 1: Doubly strong Estimation Imagine we are evaluating a training program where participants self-select into treatment. To estimate its effect on their earnings, we must account for confounders like age and education.
