Bayesian
This term describes a specific philosophical approach to probability where beliefs are updated dynamically as new data emerges. It contrasts sharply with the frequentist perspective, which views probability as the long-run frequency of repeatable events. In professional discourse, it carries a connotation of flexibility and iterative learning.
When used as a noun, it refers to a practitioner or theorist. Because it is derived from a proper name, it is consistently capitalized regardless of its position in a sentence.
Meanings

The researcher used a Bayesian approach to analyze the clinical trial data.
A person who adheres to or utilizes Bayesian statistics in their methodology or philosophical outlook.
