In probability theory, conditional independence describes situations wherein an observation is irrelevant or redundant when evaluating the certainty of a hypothesis. Conditional independence is usually formulated in terms of conditional probability, as a special case where the probability of the hypothesis given the … See more Let $${\displaystyle A}$$, $${\displaystyle B}$$, and $${\displaystyle C}$$ be events. $${\displaystyle A}$$ and $${\displaystyle B}$$ are said to be conditionally independent given $${\displaystyle C}$$ if and only if See more Two discrete random variables $${\displaystyle X}$$ and $${\displaystyle Y}$$ are conditionally independent given a third discrete random variable $${\displaystyle Z}$$ if … See more A set of rules governing statements of conditional independence have been derived from the basic definition.
