Canonical Selection
Within Sub-Version​
The canonical rate is the final rate designated as the "best" rate for a given rate object. In a particular sub-version run, we select the rate with the highest accuracy score.
Combining Sub-Versions to Create prod_combined_all​
Given four recent sub-versions (e.g. "2024_12", "2024_11", "2024_10" if current sub-version is "2025_01"), select the rate with the highest accuracy score.
If there are multiple rates with the same score, use the rate hierarchy below to select the canonical rate.
