WebbThe ICDF is more complicated for discrete distributions than it is for continuous distributions. When you calculate the CDF for a binomial with, for example, n = 5 and p = … In probability and statistics, a probability mass function is a function that gives the probability that a discrete random variable is exactly equal to some value. Sometimes it is also known as the discrete density function. The probability mass function is often the primary means of defining a discrete probability distribution, and such functions exist for either scalar or multivariate random var…
