Product Experimentation with Doubly Robust Estimation: When Both Your Models Are Wrong in LLM Applications
Rudrendu Paul's freeCodeCamp tutorial explains doubly robust estimation (AIPW) for causal inference in LLM product experiments, showing how it remains valid if either the propensity or outcome model is correctly specified. The article includes a from-scratch implementation using scikit-learn and a synthetic dataset, demonstrating how AIPW corrects selection bias in self-selected treatment groups.
