Guides

Task-oriented workflow documentation for configuration, validation, demos, lifecycle, and troubleshooting.

Pages

• Configuration guide — meridian-tools is driven by one YAML configuration file. This guide explains every section, its purpose, and its constraints. For a field-level schema reference, see yaml-schema.md.
• Validation guide — This guide explains how to choose and configure validation strategies in meridian-tools. Validation is the process of evaluating a candidate model specification on held-out data before committing to a final production fit.
• Model selection guide — This guide explains how meridian-tools supports Bayesian model selection using Leave-One-Out (LOO) cross-validation and the Watanabe-Akaike Information Criterion (WAIC). It covers when model selection is available, how to interpret the outputs, and how to compare multiple candidate models.
• Lifecycle management guide — meridian-tools treats completed runs as immutable artefacts. The lifecycle module provides tools to load, compare, and refresh past runs without mutating them. This guide explains each lifecycle operation and when to use it.
• Meridian Tools workflow guide — This guide shows the supported end-to-end agency workflow for meridian-tools. It starts with one YAML config, moves through candidate validation, separates the final full-sample fit from the validation runs, and ends with the artefacts you should hand over or inspect later. The examples in this guide stay inside the implemented package surface. They do not assume notebooks, dashboards, or unpublished helper scripts.
• Meridian Tools demo guide — This is the canonical guide to the bundled meridian-tools demos. Use it when you want one safe, reproducible, end-to-end example without client data.
• Troubleshooting — Common issues and solutions when working with meridian-tools.
