Web3.2.2 - Binomial Random Variables. A binary variable is a variable that has two possible outcomes. For example, sex (male/female) or having a tattoo (yes/no) are both examples of a binary categorical variable. A random variable can be transformed into a binary variable by defining a “success” and a “failure”. WebThe negative binomial distribution also arises as a continuous mixture of Poisson distributions (i.e. a compound probability distribution) ...
