This talk introduces a novel Python library for statistical testing using e-values, offering a refreshing alternative to traditional p-values. We'll explore how this approach enables real-time sequential testing, allowing data scientists to monitor experiments continuously without the statistical penalties of repeated testing. Through practical examples, we'll demonstrate how e-values provide more intuitive evidence measures and enable flexible stopping rules in A/B testing, clinical trials, and anomaly detection. The library implements cutting-edge methods from game-theoretic probability, making advanced sequential testing accessible to Python practitioners. Whether you're conducting A/B tests, monitoring production models, or running clinical trials, this talk will equip you with powerful new tools for sequential data analysis.

This talk introduces supplyseer, an open-source Python library that brings advanced analytics to Supply Chain and Logistics. By combining time series embedding techniques, stochastic process modeling, and geopolitical risk analysis, supplyseer helps organizations make data-driven decisions in an increasingly complex global supply chain landscape. The library implements novel approaches like Takens embedding for demand forecasting, Hawkes processes for modeling supply chain events, and Bayesian methods for inventory optimization. Through practical examples and real-world use cases, we'll explore how these mathematical concepts translate into actionable insights for supply chain practitioners.
