"WebI came across a problem where the marginal distribution of a random variable Y, f ( y) = c / y 2 and f ( x y) = 1 / y. Can I simply multiply these two to get f ( x, y) the joint distribution of X and Y, which in this case will be c / y 3. And then integrate it over all Y to find the marginal distribution of X. conditional-probability " - Marginal distribution vs conditional

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. [2]

WebA conditional distribution is a distribution of values for one variable that exists when you specify the values of other variables. This type of distribution allows you to assess the dispersal of your variable of interest under specific conditions, hence the name. That might sound a bit complex, but the idea is straightforward. 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…
