In probability theory, conditional dependence is a relationship between two or more events that are dependent when a third event occurs. For example, if and are two events that individually increase the probability of a third event and do not directly affect each other, then initially (when it has not been observed whether or not the event occurs) ( are independent). Conditional dependence of A and B given C is the logical negation of conditional independence . In conditional independence two events (which may be dependent or not) become independent given the occurrence of a third event.

dbo:abstract
  • En teoria de la probabilitat, la dependència condicional és una relació entre dos o més esdeveniments que depenen quan es produeix un tercer esdeveniment. Per exemple, si A i B són dos esdeveniments que augmenten individualment la probabilitat d’un tercer esdeveniment C i no s’afecten directament, llavors inicialment (quan no s’ha observat si es produeix o no l'esdeveniment C): (A i B són independents). Però suposem que ara s’observa que es produeix C. Si es produeix l'esdeveniment B, la probabilitat de produir l'esdeveniment A disminuirà perquè la seva relació positiva amb C és menys necessària com a explicació per a l’ocurrència de C (de manera similar, si es produeix l'esdeveniment A disminuirà la probabilitat d’ocurrència de B). Per tant, ara els dos esdeveniments A i B depenen condicionalment negativament els uns dels altres perquè la probabilitat que es produeixi cadascun depèn negativament de si es produeix l’altre. Tenim La dependència condicional és diferent de la independència condicional. En la independència condicional, dos esdeveniments (que poden ser dependents o no) s’independitzen, tenint en compte que es produeix un tercer esdeveniment. (ca)

But suppose that now is observed to occur. If event occurs then the probability of occurrence of the event will decrease because its positive relation to is less necessary as an explanation for the occurrence of (similarly, event occurring will decrease the probability of occurrence of ). Hence, now the two events and are conditionally negatively dependent on each other because the probability of occurrence of each is negatively dependent on whether the other occurs. We have Conditional dependence of A and B given C is the logical negation of conditional independence . In conditional independence two events (which may be dependent or not) become independent given the occurrence of a third event. (en)
