The COMPEL Glossary Graph visualizes relationships between framework terminology, showing how concepts interconnect across domains, stages, and pillars. Term nodes cluster by pillar affiliation while cross-references reveal semantic dependencies — for example, how risk appetite connects to control effectiveness, model governance, and assurance requirements. This network representation helps practitioners navigate the framework vocabulary and understand that COMPEL terminology forms a coherent conceptual system rather than isolated definitions.
COMPEL Glossary / propensity-score-matching
Propensity-score matching
An observational-study method matching treated and control units on estimated probability of receiving treatment, then comparing outcomes across matched pairs.
What this means in practice
Reduces selection bias where randomisation is impossible; sensitive to unobserved confounders and to the quality of the propensity-score model.
Synonyms
PSM , propensity matching
