# A/B Testing & Causal Inference Simulator

4-tab interactive dashboard demonstrating SOTA experimentation methods:

- **Power Analysis** — Sample size calculator + power curve
- **A/B Test Analyzer** — Frequentist (Z-test) + Bayesian (Beta-Binomial) + CUPED variance reduction
- **Sequential Testing** — mSPRT always-valid inference vs. peeking inflation
- **Uplift Modeling** — HTE with CausalForestDML, X-Learner, T-Learner on Hillstrom dataset
