Glossary
The following list includes the names and symbols of recurring concepts in CalibrateEmulateSample.jl. Some of these variables do not appear in the codebase, which relies on array programming for performance. Contributions to the codebase require following this notational convention. Similarly, if you find inconsistencies in the documentation or codebase, please report an issue on GitHub.
