Marginalization (probability) - The Free Dictionary

WebConditional probability Conditional probability is the probability of a variable (or set of variables) given another variable (or set of variables), denoted P(A B). For example, the probability of Windy being True, given that Raining is True might equal 50%. This would be denoted P(Windy = True Raining = True) = 50%.

The function is a probability distribution of C given each (a,b) as parameter: $ P(C=c A=a,B=b) \sim \mbox{Beta distribution of C with mean} = a b $. The variance of distribution C would be the average of the variances of distributions A and B.

The marginal probability is the probability of a single event occurring, independent of other events. A conditional probability, on the other hand, is the probability that an event occurs given that another specific event has already occurred. This means that the calculation for one variable is dependent on another variable. The conditional distribution of a variable given another variable is the joint distribution of both va…
