WebWhat is PMF used for? Probability mass function (PMF) has a main role in statistics as it helps in defining the probabilities for discrete random variables. PMF is used to find the mean and variance of the distinct grouping. PMF is used in binomial and Poisson distribution where discrete values are used. WebGiven the joint pmf, we can now find the marginal pmf's. Note that the marginal pmf for \(X\) is found by computing sums of the columns in Table 1, and the marginal pmf for \(Y\) corresponds to the row sums. (Note that we found the pmf for \(X\) in Example 3.3.2 as well, it is a binomial random variable. We also found the pmf for \(Y\) in ...
