It walks through log-log OLS regression for price elasticity (-0.491), an XGBoost vs ARIMA backtest showing XGBoost cut RMSE from 1.841 to 0.710, Welch's t-test and Cohen's d for A/B policy testing, a 1,000-run Monte Carlo stockout simulation (4.2% stockout risk), and a Streamlit dashboard wired to a hybrid OpenAI/local rule engine, later extended to Google Cloud using Vertex AI Agent Builder and a tuned Gemini model for an interactive dispatch agent. ## Full article daily.dev links to this article rather than hosting it.
