WebIn the right margin is the marginal distribution of X. In the bottom margin is the marginal distribution of Y. 3. Joint and Marginal Distributions (cont.) ... The only di erence is that the conditional distribution is a func-tion of the observed value of X. Hence its parameters, if any, are functions of X. 11. 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…
