WebRegular conditional probability. In probability theory, regular conditional probability is a concept that formalizes the notion of conditioning on the outcome of a random variable. The resulting conditional probability distribution is a parametrized family of probability measures called a Markov kernel . WebJun 4, 2024 · Another definition of a conditional distribution is as a function $ f ( \omega , B ) $ of a regular event and a Borel set such that, for fixed $ \omega $, $ f ( \omega , \cdot ) $ is a probability measure and, for fixed $ B $, $ f ( \cdot , B ) $ is a measurable function .
